Repository items correspond to business objects, like customers, and elements of business objects, like a customer’s shipping address. An item descriptor in a SQL repository defines a single type of repository item. It specifies the properties of its repository items and the database tables and columns that store these properties. This chapter describes how to define item descriptors and how to represent the relationships between item descriptors in a SQL repository definition.
Note that a SQL repository can’t necessarily work with any arbitrary SQL database model. The basic data model patterns are described in the Sample SQL Repository Definition Files section of the SQL Repository Reference chapter.
