6. Data is abstract/object relational mapping ORM

• Doctrine - Object relational mapper (ORM), requires PHP 5.2.3+ version, a very powerful database abstraction layer (DBAL).
• Propel - Object-relational mapping framework - PHP5
• Outlet - is also a tool for object-relational mapping.

Note: Object Relational Mapping (ORM) is a technology designed to solve the mismatch between object-oriented and relational databases. Simply put, ORM automatically persists objects in a program into a relational database by using metadata that describes the mapping between objects and databases. Essentially, it converts data from one form to another. This also implies additional execution overhead; however, if the ORM is implemented as a middleware, there are many opportunities for optimizations that do not exist in a hand-written persistence layer. More importantly, the metadata used to control transformations needs to be provided and managed; but again, these costs are less than maintaining a handwritten solution; and even ODMG-compliant object databases still require class-level metadata.
