COURSE OBJECTIVES:
This course introduces the basic concepts of data management and guides towards the concepts of
its application. The course emphasizes on relational data base. The course introduces normalization
and other topics like ER model, EER modeling, analysis and design techniques, relational algebra,
relational calculus and finally database security, concurrency and query optimization techniques. The
course also introduces the basics of SQL.
