Chamberlin argon the pioneers for the development of the first indication of this language . SEQUEL was the name that was addicted initially to SQL . The usance of the initial version was to work for System R . that was the certain product of IBM for relative database oversight . The initial version was designed in a way to facilitate the process of manipulation and convalescence of data that were stored in System R . thusly the formal standardization of SQL took place in 1986 by American National Standards Institute (ANSI International Organization for Standardization (ISO ) standards has alike(p) the subsequent versions of the language (Oppel ,. 90-91Vendors of SQL database management system (DBMS ) have given several variations to the originally designed SQL whose purpose was to serve as declarative query and to manipulate data language . The variations by DBMS include different procedural constructs , statements involving control-of-flow and types of user-defined data . several(prenominal) extensions in the language also took place . SQL Persistent Stored Modules (SQL /PSM were include in the basic part of the SQL language after the oust of SQL 1999 standardThough SQL was original designed to retrieve and manipulate the data from the relational database , the language can also serve as a platform for object-oriented and procedural programming and with the help of DBMS involving another(prenominal) languages . There are different elements that are involved in the sub-division of the SQL language . These elements includeStatements : The statements element affects data or schemas .

Statements are adapted for the control of flow of different programs , sessions , and transactionsQueries : Queries are responsible for the retrieval of data on the basis of particular criteriaExpressions : Expressions are fit for the productions of scalar values They can also produce tables in which rows and columns are present Those rows and columns contain data in themPredicates : In predicates , specific conditions are specified that SQL three-value logic can evaluateClauses : They are optional in certain cases . They are basically the share parts present in different queries and statementsWhitespace : The code of SQL is make easy to format by ignoring the whitespaces from the SQL statements and queries (ANSI /ISO /IEC ,. 1SQL also receives criticism from variant theorists because since its development the SQL has been widely declared as the language that is specifically designed for the use with SQL databases . It is criticized that the basic features of the SQL that were used for relational databases actually violated the relational model that was used in the management of database (Oppel ,. 90-91ConclusionSQL has been proved as a very useful language...If you destiny to get a full essay, order it on our website: Orderessay
