DB2 OLAP Server uses the Essbase OLAP engine for application design and management, data access and navigation, data load, data calculation, and application programming interfaces (APIs).
DB2 OLAP Server is compatible with Essbase, and can be used with all Essbase-ready front-end tools and applications developed by Hyperion and Essbase partners.
You can migrate your existing Essbase applications to DB2 OLAP Server.
