    The SAP DB ODBC driver allows access to the SAP DB database system. Data is accessed using the Structured Query Language (SQL). Depending on the operating system, the SAP DB ODBC driver is both 32 bit- and 64 bit- compatible. It runs on Linux, Microsoft Windows as of Microsoft Windows 95 and all UNIX systems that are supported by SAP DB.
