Software AG products that support DB2, MySQL Enterprise Edition, Oracle, PostgreSQL, or SQL Server use Java Database Connectivity (JDBC) and the DataDirect Connect JDBC database driver to communicate with those RDBMSs. The products come with the client component of this driver; it is a JDBC native-protocol driver that does not have a server component. The products use the driver to convert JDBC requests from Java programs directly into the vendor-specific database protocol that each type of RDBMS can understand. The products execute DDL commands at install time and sometimes design time for each RDBMS with which they interact. For information about the DataDirect Connect JDBC driver, see the DataDirect Connect documentation, available on the Software AG Documentation website.
