In this case, you would specify the roles they play in the association, the roles that show the entity’s participation in association. The associations of type m n are resolved through two joint 1,n and 1,m 1,n.
Grouping is done taking into account different criteria: The collection of an association cmd given by the participating entities. In the frame of economic activity, internal actors are identified with the institution or department eg. For this purpose we take into account various criteria: For entity Contract, we can set the static constraints.

But we must not exaggerate the creation of sets cardinallit input variables that will not be processed and will take up the system resources. The compound attributes comply the calculation algorithms and do not occur in conceptual entities. The cardinality express the participation of the achievements of the entities to the associations.
Such a MIS is easier developed in steps further, due adequacy of input variables.
