System Model Approaches

The systems model approach is a process-oriented representation that emphasizes the impact or flow of information between modules. The multidisciplinary study of the use of models to design and create systems in business and IT development is known as systems model approach. It models how processes interact and what these processes do, but it does not go into detail about how these processes are implemented. Functional decomposition may be utilized to enhance the models employed in this technique, and they can be coupled to requirements models for additional system partitioning.

Consider an E/R diagram which has information about students, courses, and enrollments, where Students = (Sid, Sname, address, SIN, Program) and Courses = (Cid, Cname, Credits) are the entity sets and Enrollments is a many-to-many re- lationship between them with grade as its own attribute. Give an equivalent E/R diagram (i.e., preserves the information content) in which enrollment is modeled as a weak entity set.
While it is preferable to utilize either descriptive or prescriptive models, which one is more effective?
