The meaning of ‘SQL’ in Database is ‘Structured Query Language’.
Meaning of ‘SQL’
SQL, or Structured Query Language, is a programming language used to manage data stored in relational databases. It is the most widely used language for managing and querying data in the world today. SQL has become an integral part of database management systems (DBMS) such as Microsoft SQL Server, Oracle Database, IBM DB2, and MySQL.
The term “Structured Query Language” was first introduced by Dr. E.F Codd in 1974 during his research on relational databases. The purpose of SQL was to provide users with an easier way to interact with the data stored in their databases and manipulate it to obtain desired results.
SQL is a highly structured language consisting of three primary components: Data Definition Language (DDL), Data Manipulation Language (DML), and Transaction Control Statements (TCS). DDL allows users to create and alter database objects such as tables, indexes and views while DML enables them to retrieve and modify data from those objects. TCS provides control over the transactions made within the database system.
SQL commands are written in terms of statements which are then parsed into logical expressions by the DBMS and executed accordingly. The syntax for these statements follows a set of rules known as the SQL language standard which defines how commands should be constructed for correct execution by the DBMS. This syntax also ensures that any statement written using SQL can be understood by any other compliant DBMS regardless of its underlying implementation details.
SQL can be used for various tasks including creating new databases, modifying existing ones, retrieving data from tables and views, inserting records into tables, updating records in tables, deleting records from tables, creating user authentication accounts, granting privileges to users on specific objects, controlling transactions between multiple processes accessing the same database object simultaneously etc., making it a very powerful tool for managing large amounts of data efficiently and accurately.
In addition to its capabilities as a programming language for managing data stores within database systems, SQL can also be used to generate reports using queries which allow users to get meaningful insights out of their datasets quickly without having to write complex code or manually search through large volumes of raw information.
Overall, Structured Query Language has become one of the most widely adopted tools for working with relational databases due its versatile nature which allows users both technical and non-technical alike to manage their data stores efficiently and effectively while still keeping them secure from malicious activities or other unwanted events. It has been around since 1974 but remains just as relevant today thanks to its powerful features which enable developers to build robust applications utilizing large datasets with ease while providing end-users with quick accesssible reports that give valuable insights into their businesses operations or research projects at hand.
