EntityDAC provides a powerful framework that allows you to perform object-relational mapping of database objects to Delphi classes with full support for encapsulation, inheritance, polymorphism and other OOP features. To retrieve data from a database, LINQ is used as a database independent query engine. In addition, there is a feature-rich ORM modeling tool available - Entity Developer that allows you to create and edit your ORM models visually, and generate Delphi entity classes by this model automatically.
