Creating associations


An association represents a relationship between at most two tables. Depending on the associations’ multiplicity, a table will be designated either as parent or as child.

Open ModelSphere offers two types of associations: the right-angle and the free angle associations. Both play exactly the same role, only their appearance is different.
  1. Right-click the association creation tool.

  2. Select one of the associations displayed in the ModelSphere toolbar. (While you can use any of the associations, for the purposes of this example, choose the angular line association).

  3. Click somewhere in the middle of the source table, then, in the middle of the target table.

  4. Add the associations as depicted in the following example.



If you create a recursive association and manually bring every point to the center point of the table, you will graphically lose the association. To get them back Layout entire diagram or Layout a selection of the diagram.
