Problem Set 2 - Simple two page database backed application

In the previous problem set (pset 1), we created a simple single page web application. This was a static application, because the data could not be changed.

Real world apps are dynamic where the data changes depending on user activity, or external systems. The question is where will we store this changing data. We could use the file system, but a database is a far better place to store the data.

pset 2: In this problem set, we will create a simple 2 page application.
