Andhra University Post Graduation Program,MCA : IIIrd Year - Ist Semester,Object Oriented Software Engineering Lab

To develop awareness and experience of team work directed towards engineering a nontrivial system. The teams of 3-4 students will take a project from the Instructor (act as a Client). They will deploy the UML notations and associated case tool. becoming familiar with so- ftware engineering, project management, requirement analysis, data modeling, object-oriented design, quality assurance, testing and computer-aided software engineering (CASE) in the design and development of a system software with state of the art techniques for developing complex applications.

By the end of the course students should be aware of methods applicable to the software process of large software systems.
