My university is working on a data warehouse and I was given a task to create a website (we call it "data warehouse encyclopedia, but it isn´t a widely used title"), which will have few simple purposes:
Ticket tracker - Someone (teacher, dean.. very likely doesn´t know much about IT) would like a report. So he makes a ticket "I would like some charts and tables about this". All tickets will be requests for report.
Report archive - Someone recieves a ticket, creates and saves appropriate report. Tags for searching would be useful here.
Dictionary - Something like wikipedia, basic definitions, maybe some how-to.
That's pretty much all. It has to be free software, but I don't need anything fancy with many features, just basic and simple functionality.
So my main question is - Which CMS/wiki/issue tracker would be the best choice for these requirements? Unfortunately, I have never worked with any, so I have no idea, how appropriate would any software be. I did a little research and found few candidates:
Redmine - looks like a good choice
Wordpress/Drupal/Joomla - with plugins (would you recommend any specific plugins for my task?)
Tiki Wiki CMS/Trac/Freedcamp/Dokuwiki - not sure if these are any good, but I found them while searching for alternatives.
Could anyone recommend any of mentioned software or add any additional info? Thank you very much!
