CHAPTER 6Data Foundation Basics
Within the data foundation, you are mainly specifying which tables you want accessible via the universe and their associated joins. Joins define how one or more tables relate to one another. Most of the complexities around joins occur when your universe contains multiple star schemas or when you are using SAP BusinessObjects against a transaction system with normalized data models.
This chapter explains the elements of the data foundation, join concepts, contexts, aliases, derived tables, and data foundation properties.
