Structured Query Language (SQL) is a computer language for creating database and manipulating data. SQL is an ANSI (American National Standard Institute) standard and is supported by almost all Relational Data Base Management Systems (RDBMS) like Oracle, MySQL, SQLServer, MS Access, PostGreSQL etc. SQL has two parts:
- Data Definition Language (DDL): to create, alter, or drop tables and indexes.
- Data Manipulation Language (DML): to insert, update, retrieve or delete the data in the tables.
A brief introduction to using SQL is given in my tutorial at: How To Do Things
