The development of a computer-based information system includes a systems analysis phase which produces or enhances the data model which itself is a precursor to creating or enhancing a database .There are a number of different approaches to system analysis. When a computer-based information system is developed, systems analysis (according to the Waterfall model)) would constitute the following steps:

  • • The development of a feasibility study, involving determining whether a project is economically, socially, technologically and organizationally feasible.
  • • Conducting fact-finding measures, designed to ascertain the requirements of the system's end-users. These typically span interviews, questionnaires, or visual observations of work on the existing system.
  • • Gauging how the end-users would operate the system (in terms of general experience in using computer hardware or software), what the system would be used for and so on
  • • Another view outlines a phased approach to the process. This approach breaks systems analysis into 5 phases:
    • • Scope Definition: which is denoting an instrument for observing, viewing, or examining.
    • • Problem analysis: Analyzing the problem that arises.
    • • Requirements analysis: encompasses the conditions that need to be met.
    • • Logical design: look at logical relationship among the objects.
    • • Decision analysis: where a decision is made.
