Arcavias is an e-commerce framework for Web shops, consisting of an e-commerce library, an administration interface, and different frontends. It's a modular stack which offers flexibility and speed. Unlike other Web shops, it's not a monolithic application. Instead, you have a choice between several user frontends, and you can adapt them to your needs or write one of your own.
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.
