ProductReview Example

Introduction

This page contains a description of an example project that can be used to study different implementation techniques using VDF as a backend.

In this example the overall goal is to be able to see what users think about a particular item . As an added benefit - users can also share information about where to buy the particular items.

To accomplish this, then users should be able to:

• login
• choose an item from a list
• enter information about a known item
• supply information about the place where an item was bought.
• supply a review of an item
• Overview supplied reviews from other users

The workspace is available here https://github.com/jacobandresen/ProductReview

Data Dictionaries

We want to store information about users, places and known items. The other tables should hold sufficient information about the items and how the users liked them.

The following data dictionaries should now be available (Note that attributes like "UserId" in Token implies a index on UserId on Token and a relation to the table "User")
