Software engineering 1) Suppose we wish to computerize the activities of study centers, which offer various programmers of the university. The activities are as follows :

(i) Forwarding the counselor's biodata to Regional Centre. (ii) Schedule the classes (both theory and practical) (iii) Identify Practical Centers. (iv) Collect TMA's from students and get it evaluated \l the counselors (v) Student's enquiry (vi) Dispatch of Award lists of TMA's to University

For the above mentioned system,

(1) Develop SRS. (2, Draw DFDs upto second level. (3) Identify the software modules and their functions. (4) Propose a testing strategy for any two software modules mentioned in above.
