Physical Data Areas
A data area represents a restricted physical data structure.
Creating a Physical Data Area
To create a physical data area:
1. Click the navigation menu then Data Architecture > Physical Data Assets.
2. In the edit area, 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
Diagram of a relational data area
A relational data area is made up of tables and/or physical views and can be described in two types of diagram:
• 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).Adding a component to a relational data area
You can connect objects to a relational data area through components.
A relational data area can include:
• Sub-data areas, visible in the domain structure diagram
• Tables or physical views, to which the type of access (read only, modification, deletion, etc.) is defined and which are visible in the area's table diagram.
To add a component to the data area:
1. Open the properties of the area in question.
2. Click the Components page.
The first section allows you to add objects of type table or physical view.
The second section allows you to add data areas.
3. Click New to add a component.
Defining the access mode to the referenced object
On components of type table or physical view you can define the access mode to the referenced object (creation, read-only, deletion, etc.).
To define the access mode to the object in the relational data area:
In the properties of the relational data area, select the component and select the check boxes that correspond to the types of access in question (Creation, Read-only, etc.).
