SAD CHAPTER 6

What is the purpose of system analysis?

• To define the architecture and components of a system

• To specify how the system will accomplish its objectives

• To meet the information needs of users

• To develop systems specifications

Which of the following is a quality attribute of a good system design?

• Agility

• Interoperability

• Maintainability

• All of the above

What does a conceptual data model represent?

• The physical implementation details of a system

• The high-level structure and relationships of data within a system

• The logical structure and organization of data within a system

• The actual implementation of the data structure within a system

What is the purpose of a logical data model?

• To define the physical storage structures of a system

• To specify the data types and constraints of a system

• To describe the flow of data within a system

• To provide a detailed understanding of the data requirements of a system

Which of the following is a component of system design?

• Input design

• Process design

• Report design

• All of the above

What is the purpose of a physical data model?

• To define the logical structure of data within a system

• To specify the physical storage structures and data types of a system

• To simulate the behavior of a system

• To manage and track changes to system design artifacts

Which tool is used for modeling and analyzing system designs?

• Unified Modeling Language (UML)

• Data Flow Diagrams (DFDs)

• Structured Query Language (SQL)

• All of the above

What is the purpose of version control systems in system design?

• To manage and track changes to system design artifacts

• To create interactive prototypes of the system's user interface

• To simulate the behavior of the system

• To assist in planning and tracking system design activities

What is the main objective of input design?

• To ensure the quality of system output

• To define the software resources needed by an information system

• To convey large portions of data from a database

• To convert program specifications into computer instructions

Which of the following is a characteristic of a good input design?
