This application was made for a project at school, but the customer wanted to use pen and paper instead of a proper system, it was not used for that project.
The application was made so that all operation could be done as fast as possible. Not neccessarely the easiest method, but we meant that speed was more important than learning curve. We still alloved the user to use a mouse if he was not that good at this application.
The data available in the application should be presented in a more professional way than only screen. It is therefore also a screen to print reports for selected periods.
