Getting Started with HP IMAGE/SQL

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.
