Data areas
A Data Area represents a restricted data structure dedicated to the description of a software Data Store (see Managing Data). It is made of classes and/or data views and can be described in a Data Area Diagram.
A logical data area is used to define a logical data structure made up of classes and data views.
A logical data domain is owned by a package and can reference objects held in other packages.
You can define the access mode (creation, deletion, etc.) to the objects referenced by a data area by integrating them as components of the data area.
During integration with HOPEX Database Builder, a corresponding physical structure can be defined via a physical data area. It is made up of tables and table views.
Example
The following data domain diagram represents a data structure relating to Orders; it describes classes and their relationships in a Whole/Part formalism.
To address these specific use cases, you can create Data Views in which you can see and modify the scope covered by the classes.
A data view represents the scope covered by an element of a data model or a data area. A data view is based on the selection of several classes connected in the specific context of the view.
