Build a High- Performance PHP Stack with Windows IIS and Zend Serverby Vikram Vaswani. This article was written by Vikram Vaswani of Zend Technologies Ltd. If you're a Web application developer, you've undoubtedly heard of PHP, the open- source Web programming language. PHP is an extremely popular tool for building dynamic, data- driven Web applications, as it's easy to learn, interconnects with a wide variety of RDBMSs (including Oracle, My. SQL and Microsoft SQL Server), and comes with excellent documentation and deep community support. There's only one glitch: setting up a full- fledged PHP development environment under Windows typically requires one to download, install and then configure various bits of software to talk nicely to one another. The model view controller pattern is the most used pattern for today's world web applications. It has been used for the first time in Smalltalk and then adopted.This process is something that novice developers often struggle with, and it can produce a fair amount of frustration when things don't work "out of the box". This is not a problem entirely without solutions. How-To Document. How to use the SQL Worksheet in SQL Developer to Insert, Update and Delete Data. Updated: Nov 2009 for SQL Developer 2.1. After completing this How. Review the code as follows that is contained in the query.php file in the $HOME/public_html directory. <?php // Create connection to Oracle $conn = oci. InformationWeek.com: News, analysis and research for business technology professionals, plus peer-to-peer knowledge sharing. Engage with our community. The Microsoft Web Platform offers one answer, but it certainly isn't the only one. There's also another option that you might like to consider: Zend Server, a Windows- based PHP stack that plays well with Microsoft Internet Information Services (IIS), Microsoft SQL Server and My. SQL. And over the next few pages, I'm going to show you how to use it to build a high- performance, enterprise- ready PHP+Windows stack. Getting Started. To quote its official Web site (http: //www. Zend Server is "a complete, enterprise- ready Web Application Server for running and managing PHP applications that require a high level of reliability, performance and security." Simply put, it provides a consistent and reliable PHP stack that can be easily deployed in both Windows and *NIX environments. This stack includes the latest version of PHP, some optional components (Apache, My. SQL and Zend Framework), and support for Microsoft IIS, Java, and various databases, including Oracle, My. SQL, DB2 and Microsoft SQL Server. All versions of Zend Server come with the Zend Optimizer+ opcode caching engine to significantly speed up PHP performance. Zend Server comes in two flavors, which may broadly be classified as 'commercial' and 'community'. The commercial version, known simply as Zend Server, requires purchase of a commercial license, which entitles you to software updates and technical support, in addition to goodies like page (URL) caching, automatic application alerts and diagnostics. The community version, known as Zend Server CE, is available free of charge, but lacks some of the "extras" in the commercial version. Your choice of server flavor will usually be defined by your needs (and your budget). If you're a PHP hobbyist or planning to use the server for non- critical PHP applications, Zend Server CE will probably meet all your needs. If, on the other hand, you're running critical enterprise applications and/or need technical support for your PHP environment, a commercial Zend Server license will probably serve you better. Both versions are available for Windows environments and, regardless of which one you choose, you'll get all of the following: All- in- one installation package: Zend Server provides all the key components of a PHP stack in a single point- and- click installation package. This is ideal for novice developers just getting started with PHP; it's also useful for experienced programmers who need to set up a test or development system with minimum fuss. Web- based administration: Zend Server comes with an integrated administration panel that allows administrators to monitor server status using a standard Web browser.This graphical administration panel also provides a handy way to change server configuration, set and reset PHP configuration variables, and enable or disable PHP modules. How To Manually Uninstall Crystal Reports 10 . Debugging and performance tools: Zend Server includes a number of additional components to improve application performance and make development and debugging easier.These components include Zend Optimizer+, a performance accelerator; Zend Data Cache, a data caching API; Zend Debugger, a full- featured script debugger; and Zend Java Bridge, a PHP/Java connector.All these components can be selectively enabled or disabled from the server administration console at run- time.The commercial version of Zend Server also includes event monitoring and page caching, to improve performance and reduce downtime in network environments.Certified PHP stack: The version of PHP that ships with Zend Server is tested and certified by Zend Technologies. This ensures a consistent development environment across various platforms. Having the support and reputation of a major software vendor behind the product also significantly increases the comfort level of project managers and customers who are dipping their toes into PHP- based application development for the first time. The commercial version of Zend Server also includes regular updates and security fixes, to ensure that your PHP applications remains up- to- date and protected. Enough with the advertising.. Installing Zend Server. To get started with Zend Server, download the Windows installation package from the Zend Technologies Web site. While you're there, you should request a free trial license key - this license is valid for 3. The product will automatically revert to a CE- like version, with some features disabled, once the license runs out.If you're using Windows XP Professional, Windows Vista or Windows Server 2.IIS is included with your operating system (although it is an optional installation on Windows Vista).For purposes of this article, I'll assume that you're installing Zend Server on Windows Vista with Microsoft IIS 7.If you're using a different version of the operating system, relax - the Windows installation package also works with Windows XP Professional (IIS 5.IIS 6. 0) and Windows Server 2. Audit Active Directory User Logon on this page. IIS 7. 5), with no changes necessary. I'll also assume that you have both My. SQL 5. 1 and Microsoft SQL Server Express 2. If you don't, you can get Microsoft SQL Server Express 2. Microsoft Web site, and My. SQL 5. 1 from the My. SQL Web site or via the Zend Server installer. Get things rolling by starting up the installer. You should see a welcome screen, as below: Accept the license terms, and choose a Custom Installation. At this point, you can choose which of the various Zend Server components should be installed. It's definitely worth keeping the bundled performance and monitoring tools, such as Zend Optimizer+ and Zend Monitor, and it's a good idea to install Zend Framework, which provides a set of ready- made components that simplify PHP development. I'll be showing you how to hook your PHP scripts up to Microsoft SQL Server Express and My. SQL a little further along, so also install the MS- SQL Native Client, My. SQL and php. My. Admin if you don't already have them. Next, configure Zend Server to integrate with your existing IIS web server installation. If you're using Windows XP Professional, Windows Vista or Windows Server 2. IIS should already be installed and working on your system. Confirm your choices, and let the installer go to work downloading files and setting things up. Once done, the installer will display a success message and allow you to immediately start the Zend Server process. Since this is its first run, Zend Server will prompt for an administrator password, as well as your license key. Enter the requested information and you'll be transferred to the server administration panel. Understanding The Zend Server Administration Panel. Zend Server is fully configurable via its Web- based administration panel, which is typically found at http: //localhost/Zend. Server/ and is broadly divided into four sections: Monitor: Think of the Monitor section as a one- stop shop for anything and everything related to the server's current status and health. The aptly- named Dashboard provides a quick overview of recent PHP events, such as errors and warnings, as well as information on the current status of the various Zend add- on components. This section is also the place to go to view phpinfo() output and server error logs. Under Zend Server CE, the event monitoring tools are absent. Rule Management: Two of the key selling points of Zend Server can be found in the Rule Management section: the built- in URL caching system, and the event monitoring system. The Rule Management - > Monitoring section is ground zero for the event monitor. Table of Contents. Introduction. Software Requirements. Adding Data. Inserting a Row using the Data tab. Inserting a Row using the SQL Worksheet. Modifying Data. Updating a Row. Updating Multiple Rows Using SQLRemoving Data. Deleting a Row. Unloading Data as XMLAdditional Resources. Introduction Oracle SQL Developer provides a SQL Worksheet that you can use to update data, by writing simple or complex SQL statements. In this How- To, we look at the most basic of these, inserting a record, updating single and multiple records and deleting single or multiple records. Software Requirements. Adding Data Inserting a Row using the Data tab. Inserting a Row using the SQL Worksheet. SQL Developer has a variety of methods to insert data into your table. We'll start with the most straight forward. SQL Developer makes entering data easily by using the table definition. Select the EMPLOYEES table in the Connections Navigator. Notice that some values are required. Nullable = 'No'). When inserting new rows, at least these values should be populated. Click the Data tab. What you see displayed is the current data you have in that table. Use the scrollbar to view all the rows in your table. To insert a new row click the Insert Row button. Fill in values for the required items EMPLOYEE_ID, LAST_NAME, EMAIL, HIRE_DATE and JOB_ID. To save the record to the database, click the Commit Changes button. The Data Editor log will show the Commit Successful comment when you have committed your changes. You can also insert data using the 'traditional' method you'd use when using a command line or SQL Plus. Return to the SQL Worksheet and enter the command: Insert into departments (DEPARTMENT_ID,DEPARTMENT_NAME) Values (3. Research'); Click F9. NOTE: If you click F5, the detail is shown to the Script Output tab. Notice the feedback in the message window. As before you'll need to commit the changes to save them to the database. Type Commit ; in the SQL Worksheet. Modifying Data. Updating a Row. Updating Multiple Rows Using SQLAs in the above example, you can update data using the SQL Worksheet, using SQL commands, or you can use the data tab in the table definition and update individual rows. You'll do both in this next exercise. Once again you can update rows easily by using the Data tab interface. As you did in the previous exercise, click on a table in the Connections Navigator. In this exercise, use the DEPARTMENTS table. Notice by clicking on a table different from the previous one worked on, the tab is replaced with the new selected table. To keep the EMPLOYEES tab and the DEPARTMENTS tab open, click the Freeze View pin before selecting the new object. If you always want new tabs to open, you can set a preference to pin tabs. In the last exercise you added a new record. Update that record by clicking on any of the values and changing it. Notice that once you have updated the record, an asterisk (*) shows next to the record. As before, click the Commit Changes to update the record in the database. You can use this method to update multiple records, but you still need to step through each record and click on the field to update the record. This can be cumbersome if you have multiple records. To update multiple records, it's easier to use a SQL statement. Commit; 4. Review the results of the above by returning to the data tab for the table and select refresh. SQL query in the SQL Worksheet)5. Removing Data. Deleting a Row. Deleting multiple rows using SQLAs with the previous two examples, you can use the SQL Worksheet to delete single or multiple rows, or you can use the Data tab. Return to the DEPARTMENTS data tab and select and delete the new record you inserted. This row is not deleted, i. Commit Changes button. Finally, return to the SQL Worksheet and delete a selection of rows, typedelete from departments where department_id > 2. Note: You can use F9 to execute the last statement, or F5 to execute all in the SQL Worksheet. If you want to use F5 for a single statement then you can select the statement and click F5. HINT: CTRL + Enter will execute the single statement your cursor is on. As before, these changes are not saved to the database. In order to undo any changes you have made, type. ROLLBACK; Click F9. The delete action you issued, has now been reversed. Additional Resources. Download FREE AVG antivirus software. Get protection against viruses, malware and spyware.

In recent weeks, a story about experimental Facebook machine learning research has been circulating with increasingly panicky, Skynet- esque headlines.“Facebook engineers panic, pull plug on AI after bots develop their own language,” one site wrote. Facebook shuts down down AI after it invents its own creepy language,” another added. Did we humans just create Frankenstein?” asked yet another. One British tabloid quoted a robotics professor saying the incident showed “the dangers of deferring to artificial intelligence” and “could be lethal” if similar tech was injected into military robots. References to the coming robot revolution, killer droids, malicious AIs and human extermination abounded, some more or less serious than others. Continually quoted was this passage, in which two Facebook chat bots had learned to talk to each other in what is admittedly a pretty creepy way. Bob: I can i i everything else. Alice: balls have zero to me to me to me to me to me to me to me to me to Bob: you i everything else. Alice: balls have a ball to me to me to me to me to me to me to me to me. The reality is somewhat more prosaic. A few weeks ago, Fast. Co Design did report on a Facebook effort to develop a “generative adversarial network” for the purpose of developing negotiation software. The two bots quoted in the above passage were designed, as explained in a Facebook Artificial Intelligence Research unit blog post in June, for the purpose of showing it is “possible for dialog agents with differing goals (implemented as end- to- end- trained neural networks) to engage in start- to- finish negotiations with other bots or people while arriving at common decisions or outcomes.”The bots were never doing anything more nefarious than discussing with each other how to split an array of given items (represented in the user interface as innocuous objects like books, hats, and balls) into a mutually agreeable split. The intent was to develop a chatbot which could learn from human interaction to negotiate deals with an end user so fluently said user would not realize they are talking with a robot, which FAIR said was a success: “The performance of FAIR’s best negotiation agent, which makes use of reinforcement learning and dialog rollouts, matched that of human negotiators .. FAIR’s bots not only can speak English but also think intelligently about what to say.”When Facebook directed two of these semi- intelligent bots to talk to each other, Fast. A computer virus is a type of malicious software program ("malware") that, when executed, replicates itself by modifying other computer programs and inserting its own. In recent weeks, a story about experimental Facebook machine learning research has been circulating with increasingly panicky, Skynet-esque headlines. Co reported, the programmers realized they had made an error by not incentivizing the chatbots to communicate according to human- comprehensible rules of the English language. In their attempts to learn from each other, the bots thus began chatting back and forth in a derived shorthand—but while it might look creepy, that’s all it was.“Agents will drift off understandable language and invent codewords for themselves,” FAIR visiting researcher Dhruv Batra said.

Like if I say ‘the’ five times, you interpret that to mean I want five copies of this item.This isn’t so different from the way communities of humans create shorthands.”Facebook did indeed shut down the conversation, but not because they were panicked they had untethered a potential Skynet.FAIR researcher Mike Lewis told Fast.Install Mac Os X Samsung Nc10 Manual '>Install Mac Os X Samsung Nc10 Manual . Aks Software Limited Placement Papers Of It Companies . But in a game of content telephone not all that different from what the chat bots were doing, this story evolved from a measured look at the potential short- term implications of machine learning technology to thinly veiled doomsaying. There are probably good reasons not to let intelligent machines develop their own language which humans would not be able to meaningfully understand—but again, this is a relatively mundane phenomena which arises when you take two machine learning devices and let them learn off each other. It’s worth noting that when the bot’s shorthand is explained, the resulting conversation was both understandable and not nearly as creepy as it seemed before. As Fast. Co noted, it’s possible this kind of machine learning could allow smart devices or systems to communicate with each other more efficiently. Those gains might come with some problems—imagine how difficult it might be to debug such a system that goes wrong—but it is quite different from unleashing machine intelligence from human control. In this case, the only thing the chatbots were capable of doing was coming up with a more efficient way to trade each others’ balls. There are good uses of machine learning technology, like improved medical diagnostics, and potentially very bad ones, like riot prediction software police could use to justify cracking down on protests. All of them are essentially ways to compile and analyze large amounts of data, and so far the risks mainly have to do with how humans choose to distribute and wield that power. Hopefully humans will also be smart enough not to plug experimental machine learning programs into something very dangerous, like an army of laser- toting androids or a nuclear reactor. But if someone does and a disaster ensues, it would be the result of human negligence and stupidity, not because the robots had a philosophical revelation about how bad humans are. At least not yet. Machine learning is nowhere close to true AI, just humanity’s initial fumbling with the technology. If anyone should be panicking about this news in 2. Computer virus - Wikipedia. A computer virus is a type of malicious software program ("malware") that, when executed, replicates itself by modifying other computer programs and inserting its own code.[1] Infected computer programs can include, as well, data files, or the "boot" sector of the hard drive. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.[2][3][4]Virus writers use social engineeringdeceptions and exploit detailed knowledge of security vulnerabilities to initially infect systems and to spread the virus. The vast majority of viruses target systems running Microsoft Windows,[5][6][7] employing a variety of mechanisms to infect new hosts,[8] and often using complex anti- detection/stealth strategies to evade antivirus software.[9][1. Motives for creating viruses can include seeking profit (e. Computer viruses currently cause billions of dollars' worth of economic damage each year,[1. In response, free, open- source antivirus tools have been developed, and an industry of antivirus software has cropped up, selling or freely distributing virus protection to users of various operating systems.[1. As of 2. 00. 5, even though no currently existing antivirus software was able to uncover all computer viruses (especially new ones), computer security researchers are actively searching for new ways to enable antivirus solutions to more effectively detect emerging viruses, before they have already become widely distributed.[1. The term "virus" is also commonly, but erroneously, used to refer to other types of malware. Malware" encompasses computer viruses along with many other forms of malicious software, such as computer "worms", ransomware, trojan horses, keyloggers, rootkits, spyware, adware, malicious Browser Helper Object (BHOs) and other malicious software. The majority of active malware threats are actually trojan horse programs or computer worms rather than computer viruses. The term computer virus, coined by Fred Cohen in 1. Viruses often perform some type of harmful activity on infected host computers, such as acquisition of hard disk space or central processing unit (CPU) time, accessing private information (e. However, not all viruses carry a destructive "payload" and attempt to hide themselves—the defining characteristic of viruses is that they are self- replicating computer programs which modify other software without user consent. Historical development[edit]Early academic work on self- replicating programs[edit]The first academic work on the theory of self- replicating computer programs[1. John von Neumann who gave lectures at the University of Illinois about the "Theory and Organization of Complicated Automata". The work of von Neumann was later published as the "Theory of self- reproducing automata". In his essay von Neumann described how a computer program could be designed to reproduce itself.[1. Von Neumann's design for a self- reproducing computer program is considered the world's first computer virus, and he is considered to be the theoretical "father" of computer virology.[2. In 1. 97. 2, Veith Risak, directly building on von Neumann's work on self- replication, published his article "Selbstreproduzierende Automaten mit minimaler Informationsübertragung" (Self- reproducing automata with minimal information exchange).[2. The article describes a fully functional virus written in assembler programming language for a SIEMENS 4. In 1. 98. 0 Jürgen Kraus wrote his diplom thesis "Selbstreproduktion bei Programmen" (Self- reproduction of programs) at the University of Dortmund.[2. In his work Kraus postulated that computer programs can behave in a way similar to biological viruses. First examples[edit]. The Mac. Mag virus 'Universal Peace', as displayed on a Mac in March 1. The Creeper virus was first detected on ARPANET, the forerunner of the Internet, in the early 1. Creeper was an experimental self- replicating program written by Bob Thomas at BBN Technologies in 1. Creeper used the ARPANET to infect DECPDP- 1. TENEX operating system.[2. Creeper gained access via the ARPANET and copied itself to the remote system where the message, "I'm the creeper, catch me if you can!" was displayed. The Reaper program was created to delete Creeper.[2. In fiction, the 1. Michael Crichtonsci- fi movie Westworld made an early mention of the concept of a computer virus, being a central plot theme that causes androids to run amok.[2. Alan Oppenheimer's character summarizes the problem by stating that ".. To which the replies are stated: "Perhaps there are superficial similarities to disease" and, "I must confess I find it difficult to believe in a disease of machinery."[2. Crichton's earlier work, the 1. The Andromeda Strain and 1. In 1. 98. 2, a program called "Elk Cloner" was the first personal computer virus to appear "in the wild"—that is, outside the single computer or [computer] lab where it was created.[2. Written in 1. 98. Richard Skrenta while in the ninth grade at Mount Lebanon High School near Pittsburgh, it attached itself to the Apple DOS 3. This virus, created as a practical joke when Skrenta was still in high school, was injected in a game on a floppy disk. On its 5. 0th use the Elk Cloner virus would be activated, infecting the personal computer and displaying a short poem beginning "Elk Cloner: The program with a personality." In 1. Fred Cohen from the University of Southern California wrote his paper "Computer Viruses – Theory and Experiments".[3. It was the first paper to explicitly call a self- reproducing program a "virus", a term introduced by Cohen's mentor Leonard Adleman. In 1. 98. 7, Fred Cohen published a demonstration that there is no algorithm that can perfectly detect all possible viruses.[3. Fred Cohen's theoretical compression virus[3. However, antivirus professionals do not accept the concept of "benevolent viruses", as any desired function can be implemented without involving a virus (automatic compression, for instance, is available under the Windows operating system at the choice of the user). Any virus will by definition make unauthorised changes to a computer, which is undesirable even if no damage is done or intended. On page one of Dr Solomon's Virus Encyclopaedia, the undesirability of viruses, even those that do nothing but reproduce, is thoroughly explained.[3. An article that describes "useful virus functionalities" was published by J. B. Gunn under the title "Use of virus functions to provide a virtual APL interpreter under user control" in 1. The first IBM PC virus in the "wild" was a boot sector virus dubbed (c)Brain,[3. Farooq Alvi Brothers in Lahore, Pakistan, reportedly to deter unauthorized copying of the software they had written.[3. The first virus to specifically target Microsoft Windows, Win. Vir was discovered in April 1. Windows 3. 0.[3. 8] The virus did not contain any Windows APIcalls, instead relying on DOS interrupts. A few years later, in February 1. Australian hackers from the virus- writing crew VLAD created the Bizatch virus (also known as "Boza" virus), which was the first known virus to target Windows 9. In late 1. 99. 7 the encrypted, memory- resident stealth virus Win. Cabanas was released—the first known virus that targeted Windows NT (it was also able to infect Windows 3. Windows 9x hosts).[3. Even home computers were affected by viruses. The first one to appear on the Commodore Amiga was a boot sector virus called SCA virus, which was detected in November 1. The first social networking virus, Win. Matt Larose on August 1. The virus specifically targeted users of MSN Messenger and online bulletin boards. Users would be required to click on a link to activate the virus, which would then send an email containing user data to an anonymous email address, which was later found to be owned by Larose. Data sent would contain items such as user IP address and email addresses, contacts, website browsing history, and commonly used phrases. In 2. 00. 8, larger websites used part of the Win. Operations and functions[edit]A viable computer virus must contain a search routine, which locates new files or new disks which are worthwhile targets for infection. Secondly, every computer virus must contain a routine to copy itself into the program which the search routine locates.[4. The three main virus parts are: Infection mechanism[edit]Infection mechanism (also called 'infection vector'), is how the virus spreads or propagates. Better wages. Better conditions. Better results.

As I write this post, there are air quality alerts in D.

In all these areas, children, the elderly, and people with existing breathing issues should limit outdoor time. This is just one data point in a persistent problem. In New York City alone, air pollution causes over 2,0. Day to day, the best way to avoid air pollution is to stay away from car traffic. Cars and trucks produce 2. U.

Over the long term, air pollution is falling thanks to federal regulations, according to the EPA. But the Trump- appointed EPA head is trying to roll back Obama- era emissions regulations. If you want to breathe cleaner air without hiding from cars, call your congressional representatives to say you want strong anti- pollution regulations.

This is important because if you are learning something as important as SQL, there is no point learning if you don't know which version or standard you are studying. We have diligently added as many features as possible while creating this SQL Tutorial. There is Syntax, Query, Explanation of a query and pictorial presentation to help you understand concepts better. On top of these, we have hundreds of Exercises with an online editor, quizzes. So you may practice concepts and queries without leaving your browser. SQL Queries: Introduction. ANSI SQL standards for best practices, along with a general guide and explanation of Codd's rules.In June 1. 97. 0 Dr. E. F. Codd published the paper, "A Relational Model of Data for Large Shared Data Banks" in the Association of Computer Machinery (ACM) journal. Codd's model is now accepted as the definitive model for relational database management systems (RDBMS). Using Codd's model the language, Structured English Query Language (SEQUEL) was developed by IBM Corporation in San Jose Research Center. The language was first called SEQUEL but Official pronunciation of SQL is ESS QUE ELL. In 1. 97. 9 Oracle introduced the first commercially available implementation of SQL. Later other players join in the race. Today, SQL is accepted as the standard RDBMS language. Note: If you are not habituated with database management system your can learn fromhere. What is SQL? SQL stands for Structured Query Language and it is an ANSI (American National Standards Institute) standard computer language for accessing and manipulating database systems. It is used for managing data in relational database management system which stores data in the form of tables and relationship between data is also stored in the form of tables. SQL - What is the difference between SQL and SQL Server?Answers are available for this question. more. SQL statements are used to retrieve and update data in a database. SQL works with database programs like DB2, My. SQL, Postgre. SQL, Oracle, SQLite, SQL Server, Sybase, MS Access and much more. There are many different versions of the SQL language, but to be in compliance with the ANSI standard, they support the major keyword such as SELECT, UPDATE, DELETE, INSERT, WHERE, and others. The following picture shows the communicating with an RDBMS using SQL. History of SQL Here is the year wise development history : 1. E. F. Codd publishes Definition of Relational Model.

Constructs of SQL Here is list of the key elements of SQL along with a brief description: Queries : Ret rives data against some criteria. Statements : Controls transactions, program flow, connections, sessions, or diagnostics. Clauses : Components of Queries and Statements. Expressions : Combination of symbols and operators and a key part of the SQL statements. Predicates : Specifies conditions. Some Key terms of SQL 2. To know the key terms of SQL 2. SQL 9. 2 AND SQL 2. SQL features and statements. In SQL 9. 2, SQL statements are grouped into following categories: Data manipulation : The Data Manipulation Language (DML) is the subset of SQL which is used to add, update and delete data. Data definition : The Data Definition Language (DDL) is used to manage table and index structure. CREATE, ALTER, RENAME, DROP and TRUNCATE statements are to name a few data definition elements. Data control : The Data Control Language (DCL) is used to set permissions to users and groups of users whether they can access and manipulate data. Transaction : A transaction contains a number of SQL statements. After the transaction begins, all of the SQL statements are executed and at the end of the transaction, permanent changes are made in the associated tables. Procedure : Using a stored procedure, a method is created which contains source code for performing repetitive tasks. In SQL 2. 00. 3 statements are grouped into seven categories which are called classes. See the following table : Class Example SQL data statements. SELECT, INSERT, UPDATE, DELETESQL connection statements. CONNECT, DISCONNECTSQL schema statements. ALTER, CREATE, DROPSQL control statements. CALL, RETURNSQL diagnostic statements.

SQL Arithmetic Operator Arithmetic operators are addition(+), subtraction(- ), multiplication(*) and division(/). The + and - operators can also be used in date arithmetic. SQL Comparison Operator. A comparison (or relational) operator is a mathematical symbol which is used to compare two values. SQL Assignment operator. In SQL the assignment operator ( = ) assigns a value to a variable or of a column or field of a table. SQL Bitwise Operator The bitwise operators are & ( Bitwise AND ), | ( Bitwise OR ) and ^ ( Bitwise Exclusive OR or XOR ). The valid datatypes for bitwise operators are BINARY, BIT, INT, SMALLINT, TINYINT, and VARBINARY. SQL Logical Operator. The Logical operators are those that are true or false. SQL - ANSI Standards and Guide. SQL: ANSI Standards for Database Administration. Structured Query Language, or SQL, is the standard language of database administrators (DBA) for accessing and managing databases. Throughout the years, SQL has evolved, and many versions and languages began to emerge. To unify SQL for best practices, the American National Standards Institute (ANSI) created specific standards for database query languages. The SQL Timeline. Dr. Edgar Frank Codd, a computer working for IBM publishes his famous paper, "A Relational Model of Data for Large Shared Data Banks" in June 1. Association of Computer Machinery (ACM) journal. Dr. Codd's model remains the definitive model for relational database management systems (RDBMS). IBM Corporation develops the database system, System/R, along with a database language, Structured English Query Language (SEQUEL) at their San Jose Research Center in California. They base it on Dr. Codd’s original model, and they call it SEQUEL. Relational Software, Inc., releases the first relational database management system, and name it Oracle. Their RDBMS functions on a minicomputer using SQL as the main query language. The product becomes so popular, the company changes its name to Oracle. IBM releases its first commercial SQL- based RDBMS they name the SQL/Data System, or SQL/DS, and in 1. Baixar Uma Equipe Muito Especial Legendado Absolute . Database 2 system, or DB2.Both systems run on an IBM mainframe computer.IBM ported DB2 to additional systems later, including those running on Windows and UNIX operating systems.ANSI Standards Year by Year.SQL- 8. 7 was initially formalized by ANSI in 1. The American National Standards Institute (ANSI) publishes the first set of standards for database query languages, known as SQL- 8. FIPS 1. 27- 1. 1. ANSI publishes their revised standards, ANSI/ISO SQL- 9. SQL2, which were stricter than SQLI, adding some new features. These standards introduce levels of compliance that indicated the extent to which a dialect meets ANSI standards. ANSI publishes SQL3, or ANSI/ISO SQL: 1. The replaced the levels of compliance with core specifications, as well as additional specifications for nine more packages. ANSI publishes SQL: 2. XML- related features and identity columns. The creator of the first RDBMS, Dr. E. F. Codd, passes away on April 1. ANSI publishes SQL: 2. SQL with XML and enabling applications to integrate XQuery into their existing SQL code. ANSI publishes SQL: 2. INSTEAD OF triggers, as well as the TRUNCATE statement. ANSI publishes SQL: 2. ISO/IEC 9. 07. 5: 2. ISO (1. 98. 7) and ANSI (1. SQL database query language. They split the new ANSI SQL standards into nine parts, including: Part 1 – ISO/IEC 9. SQL/Framework, which offers logical concepts. Part 2 – ISO/IEC 9. SQL/Foundation, includes central elements SQL. Part 3 ISO/IEC 9. SQL/Call- Level Interface (CLI), explains interfacing components, like procedures, structures and variable bindings for executing SQL statements in various coding languages, like COBOL and C++, for example. Part 4 ISO/IEC 9. SQL/Persistent Stored Modules (PSM), outlines standards for procedural extensions for SQL, including condition handling and the flow of control, as well as statement condition signals and resignals, and local variables and cursors. Assigns expressions to parameters and variables. Addresses the maintenance of persistent database language routines, like stored procedures. Part 9 ISO/IEC 9. SQL/Management of External Data (MED), includes extensions to SQL to define datalink types and foreign- data wrappers that enable SQL to manage external data. External data is accessible, but not managed by an SQL- based DBMS. Part 1. 0 ISO/IEC 9. SQL/Object Language Bindings (OLB), defines the semantics and syntax of SQLJ. SQLJ is the embedding of SQL into Java. The standard specifies mechanisms for the binary portability of SQLJ applications. It also defines several Java packages along with their contained classes. Part 1. 1 ISO/IEC 9. SQL/Information and Definition Schemata, specifies the Information Schema and Definition Schema, offering tools to make SQL objects and databases self- describing. Includes the SQL object identifier, security and authorization specifications, as well as the security and integrity constraints. Supports the features and packages of ISO/IEC 9. SQL- based DBMS implementations. Part 1. 3 – ISO/IEC 9. ISO/IEC 9. 07. 5- 1. SQL Routines and Types Using the Java Programming Language (JRT), Specifies the capacity to utilize Java classes as SQL structured user- defined types, as well as invoke static Java methods as routines from within an SQL application, known as Java in the Database. Part 1. 4 – ISO/IEC 9. SQL/XML- Related Specifications, defines SQL- based extensions when using XML with SQL. It outlines XML data types, routines and functions. It also describes XML to SQL data type mappings for the storage and managing of XML inside an SQL database. The ISO/IEC 1. 32. SQL Multimedia and Application Packages work alongside ISO/IEC 9. SQL. The goal of this package is to afford centralized access to the most common database applications, such as pictures, text, spatial data and data mining. How to Find a Copy of the Standards. Hard copies of SQL standards specifications are only available to buy, because of ISO and ANSI copyright restrictions. You can find an electronic copy at the ANSI website, by selecting "Access Standards - e. Standards Store" and search for "SQL Language."There are two variants of each document, but they are identical: INCITS/ISO/IEC 9. ISO/IEC 9. 07. 5- *: 2. Every database creator aims to comply with these standards, causing the various implementations of SQL to become similar; however, each implementation still has a unique dialect for using SQL that includes extensions or additions to the standards. Putting SQL to the Test. The fundamental SQL commands and statements are similar for all SQL dialects, so once a DBA knows how to use one, they can learn others easily. Although most SQL database programs have their own proprietary extensions, in order to comply with ANSI standards, they must, at the very least, support these five main commands in the same way: UPDATEDELETESELECTINSERTWHERESQL enables a DBA to conduct the following actions in a database: Execute queries. Retrieve data Insert, update and delete records Create new tables and views. Build new databases. Produce stored procedures. Set permissions for views, tables and procedures. To produce a website that can access data from a database, a Relational Database Management System (RDBMS) database program is necessary. Some popular RDBMS programs include: SQL Server. MS Access. My. SQLPostgre SQLOracle Database. In order to create a database, the database administrator will also need to utilize the following: A standard markup language like CSS/HTMLA server side scripting language, such as ASP or PHP. Understand how to use SQL to retrieve the data you request. The Anatomy of a Database. The relational database management system (RDBMS) forms the foundation of the database. Using RDBMS allows a DBA to store data in database objects, called tables. Tables consist of columns and rows of related data organized in sections. Identifying Database Tables. Most databases contain more than one table, so the DBA must identify each table with a name. Each table will contain rows of records containing information and data. For example, a business would use a database with a customer table containing the following data for each customer: Customer Name.Contact Name. Customer ID Customer Address – street, city, zip code and country Customer Contact Information.In this case, the table contains five records - one for each customer - and eight columns, one for each chunk of data: Customer Name, Contact Name, Customer ID, Customer Address including City, Zip Code, and Country, and Customer Contact Information. . Communicating with a SQL Database. Database administrators perform all the actions necessary in a database using SQL statements. The results are then stored in a result table, called the result- set. SQL is usually not case- sensitive, and some database systems require the use a semicolon at the end of every SQL statement. A semicolon has become the standard method of separating SQL statements from each other in a database system. This enables a DBA to execute multiple SQL statements in one call to the server. Some of SQL commands include: ALTER TABLE Modifies tables. ALTER DATABASE Modifies databases. CREATE DATABASE Creates new databases. CREATE INDEX Creates index/search keys.
