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

  • Understand the fundamental components of an information system.
  • Understand server-based, client-based, and client–server architectures.
  • Understand how operational, performance, security, cultural, and political requirements affect the architecture design.
  • Be familiar with how to create an architecture design.
  • Be familiar with how to create a hardware and software specification.
