You don't need to know SQL or have any programming experience to be able to take this course.

Almost three hours of video lessons and included PDF files of the database diagrams at keys steps will help you learn all about database design. The topics covered include normalisation and the normal forms, identifying tables and columns, primary and foreign keys, and setting up relationships.

The videos include explanations of the key topics in the process, as well as demonstrations on how to set up a database using an Entity Relationship Diagram. I also show you how to download and install the software that is being used for this.

We'll walk through a sample database, starting with the reason or why the database is needed, some advantages of relational databases, identify entities for the tables and attributes, create tables and columns, and most importantly, reorganise them to make the layout and design more efficient.
