DBS201 Course Outline

Course Code: DBS201
Course Name: Introduction to Database Design and SQL
Offered Date: Summer - 2019 | Other versions
Print Outline
Course Description:

This subject introduces students to relational database design and SQL (Structured Query Language) used with relational databases. Students will be introduced to  relational and object oriented models with a focus on the relational model and its operators. Students will be presented with a methodology for relational database design using Entity Relationship Diagrams and normalization of data. Students will be introduced to a subset of SQL using IBM's DB2 on the iSeries platform. An overview of the functions of the Database Management System (DBMS) and of a Database Administrator (DBA) will also be presented.
