+ PHP's database access functions are not standardised. This creates a need for a database
+ class library to hide the differences between the different database API's (encapsulate
+ the differences) so we can easily switch databases.
+
+ We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, DB2,
+ Informix, PostgreSQL, FrontBase, Interbase (Firebird and Borland variants), Foxpro, Access,
+ ADO, SAP DB, SQLite and ODBC. We have had successful reports of connecting to Progress and
+ other databases via ODBC.
