Minor fixes and updates to PHP/MySQL DB Agreement Management System
This client had hired another programmer to write a management system for their publishing records, and like so many other clients, found that the project did not go well. I was hired to clean up the mess, thinking that the core code would be usable. In the end, less than 10% of the original code was salvageable. The rest was poorly done, incomplete or just plain wrong. Even the mySQL database structures had to be significantly altered.
So, I gave them a new neat clean and working system, while retaining the old format and look/feel for ease of use. Another satisfied customer!
