Administration Services works with Essbase Servers in a three-tiered system consisting of a client user interface (UI), a middle-tier server, and one or more Essbase Servers. The middle tier coordinates interactions and resources between the UI and Essbase Servers. The tiers, which may or may not be on the same computer or platform, include the following components, as illustrated below:
Figure 36. Administration Services Architecture
Client tier (Administration Services Console): A Java-based client console provides a UI to manage the Essbase environment.
Middle tier (Essbase Administration Server): A Java-based server maintains communication, session, and security information for connections to Essbase Servers.
Database tier (Essbase Server): One or more Essbase Servers store and process multidimensional database information. Essbase Servers are installed separately from Administration Services.
