Technology Model View

Data Model View

The Data Model View covers both the logical and physical relationships among data. A logical data model shows normalized business rules and the relationships between entities. The physical model shows how this logical model would be represented in a physical database.

Rational System Architect allows a single model to be set up that contains a number of related sub diagrams to further sub divide the data into subject areas. A number of physical representations of this logical data can be maintained within the same model.

The Data Model View describes business area data at three levels: Conceptual, Logical, and Physical.

 

Location Model View

The Location Model View describes where the enterprise does business and can include particular physical facilities as well as types of locations. The "location" represents the physical location where a process or process step takes place. It does not necessarily relate directly to the organizational unit that undertakes the task.

Graphical Depiction of Locations

The Business Concept diagram enables you to graphically depict locations within your organization. You may import pictures into this diagram representing physical locations in your organization (Draw, Picture, File Copy or File Reference) and then define each picture as a location.

Location Definition

Organization Type:

A location can either be Conceptual, Logical, or Physical. A conceptual location specifies geographic location (e.g., east coast) ; a logical location provides more specific details (e.g., Boston Sales Office), and a physical location will give the exact address.
