1. Consider a system of 9 processes, P = {p1, ..., p9}. Associated with the system are 6 memory cells, M = {M1, ..., M6}. The domain and range for each process is given in the following table: Process pi Domain D(pi) p1 M1, M2 p2 M1 p3 M3, M4 p4 M3, M4 p5 p6 p7 p8 p9 M3 M4 M5 M3, M4 M5, M6 Range R(pi) M3 M5 M1 M5 M4 M4 M5 M2 M6 In addition, you are given the following precedence relation: →= {(P1,P2), (P1, P6), (P2, P3), (P2, P4), (P2,P5),(P3, P6), (P3,P8), (P4,P6), (P4,P7), (P5,P7), (P5,P8), (P6,P8), (P6,P9), (P7,P9), (P8,P9)}

We will cover the key aspects and properties of descriptive models.

Is it possible, considering the propagation approach, to completely change the look of one view in the Model-View-Controller hierarchy without impacting the Model? Justify your stance.

Here, we'll talk about the most crucial aspects of descriptive models.

What does the weak entity type really mean? What's the secret? Give an instance What does alternative specialization mean?How am I shown on the ER diagram? Give an example and create a diagram to match it.

In OOAD, visibility refers to... Explain its importance in obtaining high levels of abstraction.   What are the many types? Include illustrations and code samples to assist you demonstrate your arguments.

This is a continuation to the question above. The directions continue as follows: Also, create a Use Case diagram. Make sure to identify the entities as actors and show the interaction between each of the actors. Be sure to identify at least two processes and show all the actions between them. Don't forget to include a system boundary so we can determine which actions occur within the system and which are external to SIM.  With the creation of the use case diagram, you should be able to create a model (or table) showing each object. For each object, be sure to outline associated attributes and methods. Hopefully, the use case diagram and the DFD will make this process fairly straightforward. The developers need 3 instance examples for each of the entities. I suggest that you use the data library and previously developed organizational chart to find examples.

Select a real-life scenario that includes at least three sets of Venn diagrams. Describe why a Venn diagram is appropriate for this situation. Discuss the importance of the individual sets' intersection and union.

Using descriptive or prescriptive models is advantageous; however, which is more effective?

While it is preferable to utilize either descriptive or prescriptive models, which one is more effective?
