Avoiding Pitfalls of Spreadsheet-Based Analysis
•
Analysis based on multiple spreadsheets presents hurdles.
– Data integrity suffers because of user errors or stale data.
– Validating spreadsheet reports wastes time and resources.
•
Centralized database presents a single version of the truth.
Two spreadsheets prepared by different users show two
different totals. Which one is correct?

Providing Business Perspective
Multidimensional analysis uses a database that is
structured on business concepts and that is designed
around business needs.

Appealing to Analysts
Analysts prefer to view multidimensional data in cubes, rather
than in relational tables.
• Selection (slice and dice)
• Aggregation (roll up)
• Navigation to more detailed data (drill down)
• Visualization operations (pivot)

Essbase Business Scenarios and Training
Environment
In the classroom using a single machine, you build an Essbase
cube for each of two fictitious companies, each with its own
analytical needs.
• For Bigcorp Corporation, you build a predesigned Essbase
cube through a series of classroom exercises.
• For Country Kitchen Desserts, you design and build an
Essbase cube by completing a case study.

Business Scenario: Bigcorp Corporation
Bigcorp Corporation, a high-tech manufacturer of hard disk
drives, recently purchased Essbase. Bigcorp has designed—
but not yet built—a multidimensional analysis system for
analysis and reporting.
It needs you to build an Essbase cube that enables analysis in
three functional areas:
• Finance (costs and revenues)
• Manufacturing (volume)
• Sales (product and customer)

Business Scenario: Country Kitchen Desserts
Country Kitchen Desserts (CKD), an international food services
company, is growing at a fast pace. CKD needs you to design
and build an Essbase database that focuses analysis on cost
containment during a period of expected growth.
Analysis will be heaviest in the following areas:
• Finance (income statement and variances)
• Sales (region, salesperson, product)
