Federico Cargnelutti's Blog:
Zend Framework DAL DAOs and DataMappers
September 22, 2009 @ 08:19:51

In his latest blog post Federico Cargnelutti talks about data access layers, data access objects, data mappers and how to implement them in a Zend Framework application.

In his example code he creates a few new directories in his basic application layout under the "lib" directory to contain the files for the mapper, data access layer and data objects. He uses s simple "user" table with first and last names and an ID to help identify the row.

The User model, mapper and data access object work together to make a simple "getUser" method as easy as creating a new Project_DataMapper_User object and setting up the entity before doing the fetch with a "get" call.
