This document discusses information systems analysis and design. It covers the modern systems development approach, which includes both process-oriented and data-oriented methods. Four main types of information systems are described: transaction processing systems, management information systems, decision support systems, and expert systems. The systems development life cycle is outlined as having six phases: project identification and selection, project initiation and planning, analysis, design, implementation, and maintenance. Alternatives to the traditional life cycle like prototyping, rapid application development, and joint application design are also discussed.
