In the previous parts of this tutorial series we have discussed how to setup the application environment using XAMPP and CodeIgniter, and the application specification. We have done the analysis and design using UML use case and class diagram with free UML diagram tool StarUML.
In this part, we will discuss the database design for our application. This database is needed to hold the data for our application.
We are going to draw the entity relationship diagram (ERD) using a free tool called MySQL workbench, formerly fabForce ERD tools for MySQL. Before continuing, please download the program here and install it to your computer.
At the end of the designing process, we will create our database structure directly to a MySQL server that can be used by our application.
