DownloadFFEntityFramework is an Object-Relational Mapping Framework (O-R Mapping / Object Persistence) for .NET with built-in features like Xml-Serialization, Model-View-Controller-Framework or UndoManagement ...
All these Components use the same Meta-Base which can be definied via Attributes (Annotations) on your Business-Classes. Nevertheless differences between Xml- and Db-Serialization can be made via an enum MetaUsage (Database, Xml, Internal …). For Example you can define a Key-Column which is only used for Db-Serialization and excluded for Xml-Serialization. The same can be done with References, Delegations &c.
A special Feature is that all Metadata can be read from a comfortable Object-Model (MetaLayer) for your own needs.
