OutSystems Platform stores system information in the database and provides System Entities to manage information in your application.
Using a System Entity
To use a system entity simply add it to your eSpace as a reference: System Entities belong to the (System) eSpace.

Application Model Entities
Entities that store information about elements of an eSpace, such as: Web Screens, eSpace Entities, References, etc.
Usually this information is used in advanced situations such as documentation of an eSpace. They should be read-only.
Entities that store runtime information of your applications, such as: Site Properties or Processes.
Entities that store logging information of your applications, such as: duration of the session and visited screens.
These entities are used for monitoring and tuning eSpaces, but their access should be read-only.
