Datamappify: Entity with multiple data sources and now with lazy loading!
Compose and manage domain logic and data persistence separately and intelligently, Datamappify is loosely based on the Repository Pattern and Entity Aggregation.
Datamappify is built using Virtus and existing ORMs (ActiveRecord and Sequel, etc). The design goal is to utilise the powerfulness of existing ORMs as well as to separate domain logic (model behaviour) from data persistence.
Attributes lazy loading has just been implemented, check it out: https://github.com/fredwu/datamappify
