Using PHP's MDB2_Schema, an XML-Based Database Schema Manager

The MDB2_Schema library from the PHP Extension and Application Repository (PEAR) is a powerful solution for preserving and using database schemas for different kinds of Relational Database Management Systems (RDBMSs). Because MDB2_Schema stores database schemas in XML format, it's independent of any particular RDBMS. One can execute basic SQL statements such as CREATE, ALTER, DROP, and INSERT directly through MDB2_Schema. MDB2_Schema supports reverse engineering and the format is compatible with both Microsoft Access (.mdb) and Internet Information Server's Metabase files.
