Essbase

Essbase


Essbase—(MDB)
a multi-threaded OLAP database software that takes advantage of symmetric multiprocessing hardware platforms—is based on Web-deployable, thin-client architecture. The server acts as a shared resource, handling all data storage, caching, calculations, and data security. The Essbase Server client needs only to retrieve and view data that resides on a server.

Essbase server
All Essbase application components, including database outlines and calculation scripts, application control, and multidimensional database information, reside on a server. With Essbase, you can configure server disk storage to span multiple disk drives, enabling you to store large databases. Essbase requires a server to run a multi-threaded operating system so a server can efficiently manage simultaneous requests. A server also runs a server agent process that acts as a traffic coordinator for all user requests to applications.

Storage type: Aggregate/ Block 
Aggregate storage databases provide an alternative to block storage databases and enable dramatic increases in database dimensionality. Using aggregate storage, Essbase serves a wide range of analytic needs—financial analysis, planning, budgeting, sales analysis, marketing analysis, supply-chain analysis, profitability analytics—all from a single analytic infrastructure.

MaxL
MaxL—a multidimensional database access language that is part of Essbase Server—provides a flexible way to automate Essbase administration and maintenance tasks.
