Oracle Essbase • Standalone OLAP server now owned by Oracle ‣ Acquired as part of the Hyperion Acquisition • Adds a fully-featured OLAP server, separate to the database, as part of the Fusion Middleware family of products • End-User focused, very popular with business users • Used to power many of the Hyperion performance management applications • Similar capabilities to Oracle OLAP • Supports MDX and XML/A rather than SQL access

Essbase Analytic Capabilities • Like Oracle OLAP, it has full OLAP capabilities • Drill, pivot, select, compare, rank, sort, filter, group, stack, calculate, annotate, write-back.... • Reporting tools enabled by database “outline” • Very easy to add financial-style calculations, forecasts, allocations etc • Slightly more emphasis on the business/finance user, rather than the DBA (as with Oracle OLAP)

Cubes Accessed using MDX and XML/A • Unlike Oracle OLAP, the primary query language for Essbase is MDX • XML/A used for web-based access (very easy integration with OBIEE) • MDX is supported by Microsoft, SAP, Hyperion, the “standard” for OLAP access ‣ Pros : exposes full capabilities of the OLAP model ‣ Cons : a new language to use, SQL-based tools are incompatible With set [CUSTOMER_DIM3] as '[CUSTOMER_DIM].Levels(2).members' set [PRODUCT_DIM3] as '[PRODUCT_DIM].Levels(2).members' set [TIME_DIM3] as '[TIME_DIM].Levels(2).members' set [Q] as 'crossjoin ({[CUSTOMER_DIM3]},crossjoin ({[PRODUCT_DIM3]},{[TIME_DIM3]}))' select { [Accounts].[SALES] } on columns, NON EMPTY {[Q]} properties ANCESTOR_NAMES on rows from [global.Global]

OBIEE to Essbase Connectivity • Introduced in 10.1.3.3.2 version of BI EE • The Oracle BI Server connects to Essbase via the Essbase Client API ‣ Low-level access ‣ Precludes the use of Provider Services (implications for clustering) • Essbase Client needs to be installed on the BI Server server ‣ And potentially on the workstation running Oracle BI Administrator • BI Server generates MDX which is sent to Essbase • Able to leverage Essbase MDX functions
