OpenX serves as a platform for developing multitier enterprise applications that require access to RDBMS locally, across a LAN, Intranets, Extranets or the Internet. OpenX is an application-level database-programming interface that allows enterprise programmers to write applications from any language including C#, C/C++, JScript, Java, Visual Basic, VBScript, and provide connectivity to wide range of databases including SQL Server, Oracle, Sybase, DB2, Informix, InterBase, Centura SQLBase, MySQL. OpenX offers a fast way to connect to RDBMS, because it makes direct calls to vendor's native database APIs, thus eliminating need in all possible intermediate layers such as ODBC/OLEDB. It combines a precision and performance of custom solution with a convenience of the RAD tool.
