CHAPTER 1

INTRODUCTION TO SYSTEMS ANALYSIS AND DESIGN

Chapter 1 introduces the systems development life cycle (SDLC), the fundamental four-phase model (planning, analysis, design, and implementation) common to all information systems development projects. It describes the evolution of system development methodologies and discusses the roles and skills required of a systems analyst. The chapter then overviews the basic characteristics of object-oriented systems and the fundamentals of object-oriented systems analysis and design and closes with a description of the Unified Process and its extensions and the Unified Modeling Language.
