My goal is to prove a better data model can help us to work less. If we plan before work, we can save our resources, such as time, money, human resources and work. I would like to prove it with solving a reincurring problem: In Hungary students finishing their studies need to pass the final exam, which is organised twice a year, in each exam period. Some years ago we filed the reports by pen, nowadays we use Microsoft Office (Word, Excel), but either way, administration remained a largely mechanical, tedious task. I developed a data model, and some software to automate the task. With this solution the administrators have less work in the exam period. They can save about 8 hours per exam. The solution I propose uses free softwares1. Not only because it is free of charge, but first of all because in this case I have the freedom to change even the program codes, and anybody can download and use them without any administrative tasks. All one would need: one computer running a web server with MySQL and PHP, a printer and my software.
