Database Management System. Instructor: Prof. Partha Pratim Das, Department of Computer Science and Engineering, IIT Kharagpur. Databases form the backbone of all major applications today - tightly or loosely coupled, intranet or internet based, financial, social, administrative, and so on. Structured Database Management Systems (DBMS) based on relational and other models have long formed the basis for such databases. Consequently, Oracle, Microsoft SQL Server, Sybase etc. have emerged as leading commercial systems while MySQL, PostgreSQL etc. lead in open source and free domain. While DBMSs differ in details, they share a common set of models, design paradigms and a Structured Query Language (SQL). In this background the course would examine data structures, file organizations, concepts and principles of DBMSs, data analysis, database design, data modeling, database management, data and query optimization, and database implementation. More specifically, the course introduces relational data models; entity-relationship modeling, SQL, data normalization, and database design. It would also introduce query coding practices using MySQL (or any other open system) through various assignments. Design of simple multi-tier client/server architectures based and Web-based database applications will also be introduced.
