Here I will build a example application using the VDF Ajax library and note the steps taken underway.
Functionality
To have an example AJAX application to share assessments about known items .
To accomplish this, then users should be able to:
- login
- create a user account
- choose an item from a list
- enter information about a known item
- supply a rating of an item
The overall goal is to be able to see what users think about a particular item.
The system should be implemented using as a web application, showcasing the possibilities in the VDF AJAX library.
Development
Designing the tables
We want to store information about users, places, purchases and known items. A user should be either a normal user or an administrator. The other tables should hold sufficient information about the items purchased and how the users liked them.
