OBJECTIVES:

  • To introduce about database management systems
  • To give a good formal foundation on the relational model of data and usage of Relational Algebra
  • To introduce the concepts of basic SQL as a universal Database language
  • To demonstrate the principles behind systematic database design approaches by covering conceptual design, logical design through normalization
  • To provide an overview of physical design of a database system, by discussing Database indexing techniques and storage techniques
