  • IST 421 Course Description This course provides students with the theories, models, and analytic techniques required to develop solutions for integrating and interoperating heterogeneous applications. Basic concepts that must be applied to enable diverse applications developed under different rules and standards to process cooperatively will be explored and illustrated via a comprehensive group project. This course serves as a focused introduction to the concept that information systems must be utilized (i.e., re-used) rather than redeveloped and will give consideration to the role of users and the impact of information systems on these people.
  • IST 421 Course Overview
    • Continue study of system analysis and design
    • Introduce concepts and principles of integrating dissimilar information systems
    • Balance theory and practice
      • Lectures – concentrate on theory
      • Discussions – interactive exchange of ideas, observations, thoughts, and opinions
      • Lab – solving a problems
      • Research
        • Assessing and evaluating an integration technology
        • Supplementary readings on state of the practice
    • Emphasis on “group think”
  • IST 421 Course Objectives
    • Understand and explain basic principles of software architecture
    • Understand and explain basic principles of distributed applications and distributed databases
    • Understand the reasons behind the evolution of application systems integration and interoperability
    • Understand and explain the critical elements involved in application integration
    • Understand the impact of changes to information systems on the user
      • Need to maintain consistency in the user’s world
    • Understand and explain the concept of “single logical view”
    • Design and implement an application integration environment
    • Understand the business basis for utilizing existing information systems as an alternative to re-development
  • IST 421 Course Objectives (Continued)
    • Understand the role of and reasons for using Commercial-Off-the-Shelf (COTS) software products as alternatives to custom-developed solutions
    • Understand the fundamental criticality of system integration in the emerging e-business environment
  • What You Will Learn
    • Theories, models, terminologies, and analytic techniques for interoperating heterogeneous information systems
