Three-tier application in Java

 Three tier application  This code was written by myself and two colleagues whilst on the Advanced Java Programming Workshop. It is a "Stock Market" application which demonstrates the use of a three tier architecture consisting of a database abstraction layer, database proxy and front end application. The front end is an implementation of the Smalltalk MVC (Model View Controller) design pattern. 

The names of the classes have been changed to make the whole example easier to understand.
