SQL Data Definition
The Structured Query Language (SQL) is the standard interface to manage and access data in a relational database. Unlike many other programming languages, SQL is declarative and focuses on what should be accomplished rather than how to accomplish it. This feature allows DBMSs to optimize queries – often extensively – with minimal involvement from the programmer.
