Entity ClassesΒΆ

Entity Classes are like global Data Classes but with additional information where and how to store the data of a class and its attributes to a relational database. An Entity Class is mapped directly to a database table and the attributes of an Entity Class are mapped directly to the fields of a database table. Therefore the database schema can be generated directly out of an Entity Class. It is possible to load, save, and update entity objects with the Persistence API.

Entity Classes are created with the New Entity Class Wizard and can be edited afterwards in the Entity Class Editor. Both of those are similar to the wizard and editor for regular Data Classes, but allow to specify additional settings, that are necessary for automated persistence.
