As an example, why don’t we assume there clearly was some relationship among entities professional, venture, and Notebook. Then three many-to-many binary relationships can be defined (see Figure 4.2(a) for the ER model and Figure 4.2(c) for UML) if each technician can be working on any of several projects and using the same notebooks on each project,. If, nevertheless, each specialist is constrained to make use of precisely one notebook for every single task and therefore notebook belongs to simply one specialist, then the one-to-one-to-one ternary relationship must certanly be defined (see Figure 4.2(b) for the ER model and Figure 4.2(d) for UML). The approach to take ER modeling will be very very very first effort to convey the associations when it comes to binary relationships; should this be impossible due to the constraints associated with associations, make an effort to express them when it comes to a relationship that is ternary.
