IBM created the Db2 family of data management tools, which includes database servers. Although it was originally designed to serve the relational model, it has now been expanded to include object-relational functionality as well as non-relational structures like JSON and XML.

You can realize the benefits of using Db2 Multisystem in several ways:

Query performance can be improved by running in parallel (pieces of the query are run simultaneously on different systems).

The need for data replication decreases because all of the systems can access all of the data.

Much larger database files can be accommodated.

Applications are no longer concerned with the location of remote data.

When growth is needed, you can redistribute the file across more systems, and applications can run unchanged on the new systems
