|

| 22 | PHP's database access functions are not standardised. This creates a need for a database
|
|---|
| 23 | class library to hide the differences between the different database API's (encapsulate
|
|---|
| 24 | the differences) so we can easily switch databases.
|
|---|
| 25 |
|
|---|
| 26 | We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, DB2,
|
|---|
| 27 | Informix, PostgreSQL, FrontBase, Interbase (Firebird and Borland variants), Foxpro, Access,
|
|---|
| 28 | ADO, SAP DB, SQLite and ODBC. We have had successful reports of connecting to Progress and
|
|---|
| 29 | other databases via ODBC.
