IBM Data Server Driver for ODBC, CLI, and. NET also provides some very good Windows enhancements. For example, an installation wrapper is included that can significantly enhance the deployment features on Windows. This driver also provides a set of merge modules,

Many technicians can easily discuss the details of DB2 technology and confidently talk about query parallelism, data compression, WebSphere MQ integration, large object management, JDBC and ado.net drivers, data sharing on mainframe Parallel Sysplex, DB2 for Lin UX, Unix, and Windows (LUW) multidimensional clusters, and so on. But what happens if the person who talks is a member of the management? The main
