Sybase Open Client 

Open Client is a versatile programming interface allowing transparent access to any data source, information application or system service. A library of routines, programming services, and runtime services for application development, Open Client allows custom programs, tools from Sybase, and non-Sybase products to communicate with the Adaptive Server family , with applications developed using Open Server, and with any number of other data sources supported by the ODBC standards and other API’s. You spend time developing, not addressing interoperability issues.
