Base Objects

All application objects needed to execute 4GL applications are stored as XML documents in the (remote) application repository. All these objects are stored with the following unique key combination:

  • Application

  • Object

  • Name

There are two types of these base objects:

  1. System Objects these objects apply to the environment in which applications run. The objects will be stored in the administrator application.

  2. Application Objects these objects apply to a specific application only.
