Using the data object editors


We've mentioned the Table Editor previously which is the data object editor for editing tables. We used it in Chapter 2 to create our source metadata definitions for the ACME_POS transactional database, so let's take this opportunity to look a little closer at the editors for a dimension and a cube. We'll also discuss the overall Design Center interface and some of the other windows available to us in that interface as we're editing objects.
