1. System Controls are an important aspect of System Design. Controls can be viewed as either “Integrity Controls” or ‘Security Controls”. Use Table 6 and please list as many examples of each of these two types of System Controls.
2. System Design describes four (4) Distributed Database Architectures. For each Architecture listed in Table 5, please provide a definition / description.
3. What is a “Database Schema”? define its role within System Design
4. A Human-Computer Interface (a human interface to a computerized machine) can be thought of as having three (3) key aspects. Define in the following by reproducing Table 4.
5. What is “User Centered Design” and what are its three (3) Key Principles? Please explain
6. In Detailed (Low Level) Design, two (2) approaches for Use Case Realization are Sequence Diagrams and Communication Diagrams. Use the Table 3 to define each:
7. In System Design, what are “CRC Cards”, and what are their purpose?
8. System Design demands that Design Class Methods be defined. What is a “Method” as it relates to “System Design” and “Design Classes”?
9. In Systems Analysis, UML diagrams such as the System Sequence Diagram and the Domain Model Class Diagram are created. For each of these two (2) diagrams, what isdone to them in System Design?
10. System Design introduces the “fundamental design principles” of Coupling, Cohesion, and Protection from Variation, Indirection and Object Responsibility. In the following table, please define each of these “fundamental design principles”.
11. If you view “Systems Analysis” as development of a “Ready to Design” version of a “System of Interest”, then “System Design” can be described as a “Ready to Implement” version of the same system. Explain what a “Ready to Implement” level of detail means to you.
12. Research the topic “Mobile First Design”. Provide a paragraph description as to what “Mobile First Design” means.
13. System Design introduces at least four (4) “hosting alternatives for Internet deployment”. list the four (4) identified “hosting alternatives”.

a. list and explain the three “Layers” of this Architecture
b. define the “Three Layer Client-Server Architecture”

14. The topic of Design introduces “Three Layer Client-Server” Architecture”. With that in mind, please answer questions “6a.” and “6b.” below:
15. Project 2A introduces the concept of “Architectural” or “High Level” Design as well as “Detailed” or “Low Level” Design. What are the key differences between these two levels of “Design”?
16. Our textbook says “Think of Design as just extending the models begun in Analysis”. What does the text mean by “extending the models’?
17. Based on what you have learned to date in this course, what are the primary outputs of “Systems Analysis” that in turn become the primary inputs to “System Design”? Be specific and complete,
18. According to our textbook, what are the six (6) primary System Design activities?
19. In your view, what is the primary difference between “Systems Analysis” and “System Design’? Be as specific as possible.
