Oracle Parallel Servers Extend Window NT's capabilities by enabling a set of nodes to share work in the same cluster, providing high-availability and highly scalable clusters of solutions. If WindowsNT does not meet the needs, users can move the database to UNIX. The DB2 DB2 has good parallelism. The DB2 extends the database management to the parallel, multi-node environment.

However, the stability and reliability of the Windows operating system are obvious to all, and Microsoft's strategic goal is to lock customers into the Windows Platform environment, and SQL Server can be improved only with the improvement of Windows performance. From the operational platform, Oracle is completely superior to
