CS 311 Systems Analysis and Design3 units lecturePrerequisite: CS213Placement: Third Year

Course Description:

This course introduces the concepts and techniques of information systems analysis, especially on the part of data gathering and requirements analysis, in the context of the Systems Development Life Cycle. Several models and tools for information systems analysis are presented.Objectives:

At the end of the semester, students are expected to:

1. Identify data to be gathered for an information system project and the techniques and tools for gathering such data.2. Model organizational data and systems as basis for analysis

3. Identify data and system requirements as a result of system analysis.

4. Recommend solutions or opportunities in the development of a system proposal or software requirement specification.

5. Develop designs for system solutions.
