Creating Data Models
The MEGA Suite for DoDAF 2 can be used to design data models. The data model is a concept that can be graphically designed in Data model diagrams. The user creates new data models from the DoDAF 2.0 start page or navigation tree.
The data models are described by one or more data model diagrams, which contain entities with their attributes and the associations between the entities.
Example of a data model
The entities should correlate with the OV-3 information elements. These elements are modeled with the MEGA content objects and the content can be linked to a data model.
An information model should be based on the AV-2 model, which actually forms the operational domain object model and which contains the definitions of all the concepts that are relevant for the architecture effort. In turn, DIV-1 should be used as an input to DIV-2 and DIV-3, which capture logical and physical data models.
