Microsoft® Repository stores metadata as data. This section uses data visualization techniques to demonstrate how to model metadata. (See Ways to List Data for a table listing and organizing the data about books and publishers.)

The Kind of Data column thus reveals a portion of the object model for storing classes and relationship types.
