CP363 DATABASE I, FALL 2022, WLU

Course Description

The course provides an introduction to the basic features of Database Management Systems (DBMS), focusing on Relational Database Management Systems (RDBMSs). Students will obtain an understanding of how the different components of a DBMS system fit together. They will write programs to interact with a particular DBMS as a case study.
