Adding OData Elements to the OData Service
Entity types are named structured types with a key. For example, uniquely identifiable records such as a Customer or Employee. Complex types are structural types consisting of a list of properties but with no key. For example, Address, which includes city, street, state, and country. External entity types are entity types available through an external source provider. For example, if you choose to use webMethods Adapter for JDBC as your external source provider or source type, you can use Database Tables as entity types to create your entities.
