Here is a CAD system I made using Access 2010. It will only work with Microsoft Access 2010 no earlier. I have yet to try open office, if you have it let me know if it works with this.
Just save it to your desktop or network if you have multiple workstations. Double click on it, when it opens there will be an enable content option, make sure you do this. Once that is done login with the following login, username: DISPATCH password: POLICE. They have to be capitalized.
It is all yours to experiment with, it is very simple. Click incident to add a call. The call will update in Unit Status and the Reports section. In Reports you can click on a call on the bottom of the screen and file the report for the call.
It is not too in depth of a program considering I am just out of highschool, but I saw your post, just hoping this could help. Let me know your opinions.
Here is the database to download....
COMPUTER AIDED DISPATCH.accdb download - 2shared
Just click the blue download then save it to your desktop, and begin call logging.
If you have any questions feel free to send me a PM I would be more than happy to help.
