∟What Is SQL

This section provides a quick introduction of SQL (Structured Query Language), a computer language that allows users to interact with RDBMS to define create data structure and manage data instances.

What Is SQL? SQL (Structured Query Language) is a computer language that allows users to interact with Relational Database Management Systems (RDBMS) to define data type and structure, and to insert, update or delete data instances.

Usually, an RDBMS system will offer a user interface (UI) to allow you to issue SQL statements to directly operate on the RDBMS system: 

User <--> UI <--SQL--> RDBMS <--> Data storage

A typical RDBMS system does also offer Application Programming Interface (API) to allow application programs to use SQL statements to interact with the RDBMS system: 

User <--> Application <--SQL--> RDBMS <--> Data storage

SQL is a non-procedural language. Each SQL statement is an individual execution unit, independent of other statements. There is no conditional statements, jumping statements or looping statements to group multiple statements together into a complex execution unit. There is no way to define a procedure of statements, and no procedure call statements.
