Introduction

Information Systems Analysis and Design

  • Complex organizational process whereby computer-based information systems are developed and maintained

Application Software

  • Computer software designed to support organizational functions or processes

Systems Analyst

  • Organizational role most responsible for analysis and design of information systems
  • A Modern Approach to Systems Analysis and Design
    • 1950s: focus on efficient automation of existing processes
    • 1960s: advent of 3GL, faster and more reliable computers
    • 1970s: system development becomes more like an engineering discipline
    • 1980s: major breakthrough with 4GL, CASE tools, object oriented methods
    • 1990s: focus on system integration, GUI applications, client/server platforms, Internet

    • Process orientation

Management Information Systems (MIS)

    • Converts raw data from transaction processing system into meaningful form
    • Data orientation

Decision Support Systems (DSS)

    • Designed to help decision makers
    • Provides interactive environment for decision making

Involves data warehouses, executive information systems (EIS)

    • Database, model base, user dialogue
    • SummaryIn this lecture we learned about:
      • Information systems analysis and design.
      • The different types of information systems.
      • The phases in the information Systems Development Life Cycle (SDLC).

Overview of Next lecture

We will continue our discussion on SDLC

Precisely, we will talk about the problems with the existing waterfall approach

We will also see some other SDLC: Methodologies
