    Study Notes

    System Analysis and Design

    • System Analysis and Design involves five steps: systems planning, systems analysis, systems design, systems implementation, and systems support and security.

    Types of Analysis

    • Structured Analysis: SDLC model includes five steps, with a focus on systems planning, analysis, design, implementation, and support and security.
    • Object-oriented Analysis: combines data and processes that act on the data into objects, which possess properties and can be manipulated through methods and messages.

    Development Methods

    • Agile Methods: emphasize continuous feedback, iterative development, and the Agile Manifesto; examples include Scrum and Extreme Programming (XP).
    • Other Development Methods: Joint Application Development (JAD), Rapid Application Development (RAD), Rational Unified Process (RUP), V model, and DevOps model.

    Components of an Information System

    • Software: programs that control the hardware and produce the desired information or results; consists of operating systems, application software, and utility programs.
    • Data: raw facts that an IS transforms into useful information, with no inherent meaning; cannot be used for making decisions.
    • Hardware: includes mobile devices, servers, and other equipment.
    • People: includes users, analysts, and developers.

    Types of Information Systems

    • Enterprise Computing Systems: support company-wide operations and data management requirements; examples include Enterprise Resource Planning (ERP) systems.
    • Transaction Processing Systems: involve large amounts of data, are mission-critical, and update records and generate reports; examples include bill systems, payroll systems, and stock control systems.
    • Business Support Systems: designed to take relatively raw data and convert it into a summarized and aggregated form for managers; examples include Management Information Systems (MIS) and Sales management systems.
    • Knowledge Management Systems: called expert systems, simulate human reasoning, and use fuzzy logic.
    • User Productivity Systems: enhance the productivity and efficiency of individual users, manage time efficiently, and facilitate collaboration.
