Consider the Zagi Retail database. Do the following: 1. Identify ONE front-end application that would be helpful for end users. 2. Briefly explain why this front-end application would be useful (i.e., explain what it would be used for). 3. Design a mock-up of the front-end application. You can do this in MS Word or MS Powerpoint, or any drawing tool you have access to. It should give us an idea of what the application will look like..
