(Doctrine) ORM

• Object-Relational Mapping

• Pros

• • Easy to use
  • Less development code
  • Less “raw” SQL
  • Allows easy access to data:
  • • $user->Person->age (where user and person are separate tables but linked via a foreign key)

• Cons

• • Can sometimes be difficult to do complex queries
  • Requires PHP 5.1 & MySQL 5+ (if using MySQL)
