What Is SQL?
SQL is the acronym for Structured Query Language, which is defined by
ANSI standards in the United States and by X/OPEN standards in Europe.
The way into a relational database is through a query language, which is
a set of operators, expressions, and statements that let you manipulate
the database in various ways. You create queries, as well as other kinds
of statements, in IMAGE/SQL by using SQL. You issue the statements
directly through an interactive command processor (ISQL) or indirectly
through an application program.
SQL includes statements that let you do the following:
* Create databases
* Access databases
* Provide security
* Promote data integrity
* Regulate concurrent access
SQL statements are shown in uppercase letters (for example, SELECT) in
this manual.
