Laboratory Works

Students practice analysis and design of real world applications using CASE tools such as MS-Visio, MS-Project Manager, and Rational Rose. Students design data and process models using ER Diagrams, DFD, and UML Diagrams, and practice Gantt Charts and PERT Charts. A group project involving full analysis and design of a real world application is highly recommended, documented in a proper report structure.
