The OpenDBX libraries provide a unified and consistent API for software developers to different database management systems. The C and C++ libraries aim to implement access to the native database interfaces efficiently via a thin abstraction layer. They consist of a basic set of functions that are part of all vendor database libraries and can be extended by additional function blocks. Currently, Firebird/Interbase, MS SQL Server, MySQL, ODBC, Oracle, PostgreSQL, SQLite 2 and 3, and Sybase ASE are supported.
DBENGINE is a management system for using the database system PostgreSQL via browsers like Firefox. You can build multiple databases and configure and use them without logging into the server system. To use the databases, you only need a browser. The system gives you the ability to add own procedure for designing listings and input formulas. You can use binary large objects like any other type of field.
