The generator creates code based on standards of the day. The entity objects are based on a hierarchy of interfaces and base classes. Each object can describe metadata about itself like type, size, friendly name, façade, etc. The generated framework implements industry standard software patterns as well. All business objects object implement the Observer pattern for field notifications. The Active Record pattern is used as the main interface with the database. This allows for fast and very flexible querying techniques. For more disconnected requirements, the DTO layer implements the Repository pattern. This separates database access from the developer and allows objects to be sent over the wire. The Visitor pattern is employed on all business collections to allow abstracted iteration or processing on collection objects. The Composite pattern is used to define entity relationships. Dependency walking is a relationship hierarchy that requires no special coding on the part of the developer. All entities have composite objects of their children and parents. This also aids in joining objects with no visible join clauses or statements like SQL. The Interpreter pattern is implemented in the mapping of database objects to .NET entity objects. All entities and fields can have a facade that masks the underlying database field. Keep in mind that one entity can map to multiple database tables and relationships. All of these coding standards are implied in the generated code and derived from the model. No special architectural knowledge is necessary to use these concepts.
