This video, which is based
This video, which is based on a case study, shows how to build a dimensional data model for multiple business processes.
You will learn about the Types of Fact Tables, Conformed Dimensions, Role Playing Dimensions, 4-Step Dimensional Design Process, Matrix Design, Star Schema and Understand Dimensional Modeling of Multiple Business Processes based on a case study
Dimensional Data Model is a denormalization technique invented by Ralph Kimball. In this model, there are two types of tables:
- Fact Table which contains: Metrics, Foreign keys of associated dimensions, optional Degenerated Dimension, optional Audit information
- Dimension Tables are the Descriptive entities associated with the fact table
A Dimensional Model Design, has a fact table is surrounded by dimension tables, this design is referred to as Star Schema
