We have our entire source structures defined in the Warehouse Builder. But before we can do anything with them, we need to design what our target data warehouse structure is going to look like. When we have that figured out, we can start mapping data from the source to the target. So, let’s design our target structure. First, we’re going to take a look at some design topics related to a data warehouse that are different from what we would use if we were designing a regular relational database. We’ll then discuss what our design will look like, and after that we’ll be ready to move right into creating that design using the Warehouse Builder in the next topic.
The specific topics we’ll discuss in this topic include the following:
• Data warehouse design
° Dimensional design
° Cube and dimensions
° Dimensional Model Implementation
° Relational (star schema)
° Multidimensional (OLAP)
° Designing the ACME data warehouse
° Identifying dimensions
° Designing the cube
• Data Warehouse Design in OWB
° Creating a target user and module ° OWB design objects
