SQL is Structured Query Language, which is a computer language for storing, manipulating and retrieving data stored in a relational database.SQL is the standard language for Relational Database System. All the Relational Database Management Systems (RDMS) like MySQL, MS Access, Oracle, Sybase, Informix, Postgres and SQL Server use SQL as their standard database language.
SQL is widely popular because it offers the following advantages ,Allows users to access data in the relational database management systems.Allows users to describe the data.Allows users to define the data in a database and manipulate that data.Allows to embed within other languages using SQL modules, libraries & pre-compilers.Allows users to create and drop databases and tables.Allows users to create view, stored procedure, functions in a database.Allows users to set permissions on tables, procedures and views.
When you are executing an SQL command for any RDBMS, the system determines the best way to carry out your request and SQL engine figures out how to interpret the task.
There are various components included in this process.
These components are −
- Query Dispatcher
- Optimization Engines
- Classic Query Engine
- SQL Query Engine, etc.
SQL is designed for a specific purpose: to query data contained in a relational database. SQL is a set-based, declarative programming language, not an imperative programming language like C or BASIC. However, extensions to Standard SQL add procedural programming language functionality, such as control-of-flow constructs.
