Detailed Description

represent an SQL database schema

This class stores the information required to create an SQL database from scratch. Information on each table's columns, indices, and triggers is stored. You may also store an arbitrary number of preamble statements, intended to be executed before any tables are created; this provides a way to create procedures or functions that may be invoked as part of a trigger action. Triggers and table options may be specified differently for each backend database type you wish to support.

Thanks:
Thanks to Philippe Pebay and David Thompson from Sandia National Laboratories for implementing this class.
