System Analysis and Design, Fifth Edition

CHAPTER 8

ARCHITECTURE DESIGN

An important component of the design phase is the architecture design, which describes the system's hardware, software, and network environment. The architecture design flows primarily from the nonfunctional requirements, such as operational, performance, security, cultural, and political requirements. The deliverables from architecture design include the architecture design and the hardware and software specification.

OBJECTIVES

• Describe the fundamental components of an information system.
• Describe server-based, client-based, and client–server architectures.
• Describe newer architectural options, such as cloud computing.
• Explain how operational, performance, security, cultural, and political requirements affect the architecture design.
• Create an architectural design.
• Create a hardware and software specification.
