Add Many-to-Many Relationship Between Data Objects and Business Objects

[bcler]

Description
Currently, a Data Object (DO) can be linked only to one Business Object (BO). However, some applications use the same data object to model multiple Business Objects.

In the example below, we have a Party BO that is specialised by a Customer BO and a Prospect BO.
In Salesforce, both BOs are implemented via the Account DO.

To represent this, we have to create the Account DO twice.

Requested change

• Implement a many-to-many relationship between Data Objects and Business Objects to avoid the duplication of DOs

The purpose of the Golden Sources and Replicas Data Objects Viewpoints is to document where are golden and replicas in the company.

In the current implementation, each 'database' symbol represents a DataObject, but could be seen as the representation of the SINGLE associated BusinessObject. In your exemple, we could have

1. a golden source symbol for Party (Business Partner)
2. a replica symbol for Account (Prospect)
3. a replica symbol for Account (Client)

With the new many-to-many relationship, what do you think should be drawn on the diagram? And what we should write in the legend ?

Alternative discussed with @jiujiu

Could allow in the legend to group all DO by BO
