Hyperion Product Suite




What is Essbase?

It is a multidimensional database that enables Business Users to analyze Business data in multiple views/prospective and at different consolidation levels. It stores the data in a multi dimensional array.

Minute->Day->Week->Month->Qtr->Year
Product Line->Product Family->Product Cat->Product sub Cat

Introduction to Essbase





Online Analysis Processing(OLAP)

It enables analysts, managers and executives to gain insight into data through fast, consistent, interactive access to a wide variety of possible views of information that has been transformed from raw data to reflect the real dimensionality of the enterprise as understood by the user.


Overview of OLAP

OLAP can be defined as a technology which allows the users to view the aggregate data across measurements (like Maturity Amount, Interest Rate etc.) along with a set of related parameters called dimensions (like Product, Organization, Customer, etc.)


Relational OLAP (ROLAP)


Relational and Specialized Relational DBMS to store and manage warehouse data

OLAP middleware to support missing pieces

• Optimize for each DBMS backend
• Aggregation Navigation Logic
• Additional tools and services

Example: Micro strategy, MetaCube (Informix)



Multidimensional OLAP (MOLAP)

  • Array-based storage structures
  • Direct access to array data structures
  • Example: Essbase (Arbor), Accumate (Kenan)

Domain-specific enrichment





Key Features of OLAP applications

  • Multidimensional views of data
  • Calculation-intensive capabilities
  • Time intelligence

**Key to OLAP systems are multidimensional databases.

  • Multidimensional databases not only consolidate and calculate data; they also provide retrieval and calculation of a variety of data subsets.
  • A multidimensional database supports multiple views of data sets for userswho need to analyze the relationships between data categories

Ex: Did this product sell better in particular regions? Are there regional trends?

Did customers return Product A last year? Were the returns due to product defects?


What is Multidimensional Analysis


Multidimensional Analysis


A multidimensional database supports multiple views of data sets for users who need to analyze the relationships between data categories. For example, a marketing analyst might want answers to the following questions:

  • How did Product A sell last month? How does this figure compare to sales in the same month over the last five years? How did the product sell by branch, region, and territory?

  • Did this product sell better in particular regions? Are there regional trends?

Multidimensional databases consolidate and calculate data to provide different views. Only the database outline, the structure that defines all elements of the database, limits the number of views. With a multidimensional database, users can pivot the data to see information from a different viewpoint, drill down to find

more detailed information, or drill up to see an overview.










Operations In multidimensional Analysis

Aggregation (roll-up)

  • dimension reduction: e.g., total sales by city
  • summarization over aggregate hierarchy: e.g., total sales by city and year -> total sales by region and by year
Selection (slice) defines a sub cube

  • e.g., sales where city = Palo Alto and date = 1/15/96
Navigation to detailed data (drill-down)

  • e.g., (sales - expense) by city, top 3% of cities by average income
Visualization Operations (e.g., Pivot)


Multidimensional Data Model

Database is a set of facts (points) in a multidimensional space

A fact has a measure dimension

  • quantity that is analyzed, e.g., sale, budget, Operating Exp,
A set of dimensions on which data is analyzed
  • e.g. , store, product, date associated with a sale amount

Dimensions form a sparsely populated coordinate system

Each dimension has a set of attributes

  • e.g., owner city and county of store
Attributes of a dimension may be related by partial order

  • Hierarchy: e.g., street > county >city
  • Lattice: e.g., date> month>year, date>week>year
