An ORM library for CodeIgniter that builds on CodeIgniter's existing ActiveRecord library. Despite its name, it does not use the DataMapper pattern, but is instead an implementation of the ActiveRecord pattern.

DataMapper is an Object-Relational Mapper that builds on ActiveRecord. Data is loaded from database tables into objects, and relationships can be managed through simple, easy-to-read functions.

DataMapper ORM adds several important features to original DataMapper library, further enhancing it's usage, usually without requiring any code changes.

DataMapper offers these features:

  • Everything is an object!
  • Easy to setup, easy to use.
  • Custom Validation on object properties.
  • Lazy Loading (related objects are only loaded upon access).
  • Relations and their integrity are automatically managed for you.
  • One to One, One to Many, and Many to Many relations fully supported.
  • Select data in the style of Active Record (with or without Method Chaining).
