This topic describes how to map associations. The Association Mapping Details window allows you to map an association, and specify the column to property mappings.
Entity Developer also allows you to create a QueryView mapping. Query View can be used when default mapping from the entity
framework does not meet your need, and you need more flexible mapping.
