Data is abstract/object link ing ORM

1. ADOdb-database abstraction
2. Doctrine-Object relational ing Object relational mapper (ORM) requires PHP 5.2.3 +, a very powerful database relational action layer (DBAL ).
3. Propel-object relationship ing framework-PHP5
4. Outlet-is also a tool for object link ING.

Note: Object Relational ING (ORM) is a technology designed to solve the mismatch between objects and Relational databases. To put it simply, ORM automatically persists the objects in the program to the relational database by using metadata that describes the ing between objects and databases. In essence, data is converted from one form to another. This also implies additional execution overhead. However, if ORM is implemented as a middleware, there will be many opportunities for optimization, which do not exist in the handwritten persistence layer. More importantly, the metadata used to control the conversion needs to be provided and managed; however, these costs are less than the manual maintenance solution; in addition, even object databases that comply with the ODMG specifications still need class-level metadata.
