UNIFIED MODELING LANGUAGE LAB PROGRAMMS
- The student should take up the case study of Unified Library application which is mentioned in the
theory, and Model it in different views i.e Use case view, logical view, component view, Deployment
view, Database design, forward and Reverse Engineering, and Generation of documentation of
the project.
- Student has to take up another case study of his/her own interest and do the same what ever
mentioned in first problem. Some of the ideas regarding case studies are given in reference books
which were mentioned in theory syllabus can be referred for some idea.
