Automatically generating code and related artifacts such as application programming interfaces (APIs) and related documentation from an abstract model of a database. The abstract model is derived from a physical model which may be a source such as a legacy database, an entity relationship diagram, or other schema defining the data tables, objects, entities, or relationships etc. of the source. The generated code may be exposed (that is, made visible to the developer in its pre-compiled state) and further configurable and extendable. Any such extended code is maintained separately from generated code. An API and related documentation are also generated from the same abstract model.
