Physical data areas
A physical data area is used to define a physical data structure made up of tables and/or physical views.
Creating a physical data area
To create a physical data area:
1. Click the navigation menu, then Physical Data.
2. In the navigation pane, click Physical Data Areas.
There are three types of physical data areas:
• Relational data area: represents a set of data stored in a database management system and used in the technical architecture of an application.
• Non SQL data area: represents a set of data stored in a NOSQL database management system and used in the technical architecture of an application.
• File structures
3. Select the type of data area and click New.
The new data area is created. You can open its properties to modify or add to its characteristics.
Relational Data Area
A relational data area can be described by two types of diagrams.
• the table diagram which is used to display a set of tables and their relationships (FK).
• the structure diagram that is used to break down an area into sub-areas.
You can connect one or more diagrams to a data area, according to what you want to describe.
To create a diagram from a relational data area:
Right-click on the physical data area and select New followed by the type of diagram (tables or structure).The physical data map
A physical data map is an urbanization tool for physical information. It represents a set of physical data areas in a particular context.
Creating a physical data map
To create a physical data map:
1. Click the navigation menu, then Physical Data.
2. In the navigation pane, click Physical Data Maps.
3. Select the type of physical data map.
4. Click New.
The map created appears.
To create a physical data map diagram:
1. Right-click on the map and select New > Data Map Diagram.
The diagram appears in the edit area.
The components of a physical data map
You can add internal and external components in a physical data map.
The internal components are data areas that are part of the map scope (whether they belong to the same owner element or not).
The external components are those used in the map but that are not part of the scope analyzed.
