After creating the business model, the next step is to add the business tables and business columns, then create the relationships between our business tables.
Introducing the Metadata Editor Graph
Up to this point, we have only used the Tree Navigator to construct the business objects. The big white canvas on the right side of the screen is the Metadata Editor Graph, and we use the Graph to lay out our business tables and show the relationships between them. While we can accomplish the rest of our tasks using only use the Tree Navigator, from her forward I will describe how to perform each operation using both the Tree Navigator and the Graph, so you can decide which view suits you better.
