Cognos is huge. http://www.cognos.com/
It is a mainstream tool that is integrated into our product so it's not prorietary but it is an integration.. There are professional training courses, books and tons of online resources for Cognos that would enhance your experience with the Cognos that is integrated into our product. Daptiv offers an introduction course to our Advanced Report Builder and soon we will offer further, more advanced training beyond the indroduction course - the benefit will be a better understanding of the data, but writing a report and the Cognos featureset is the same from nearly any instructor because it is the same tool.*
Search Amazon for "Cognos", search google for "Cognos Books". If you can't find any I'll post up links, but I know Amazon returned the usual fare of How To's and the typical Dummy series.
* There are some features not yet integrated in our use of Cognos and I'm talking version 8 compared to version 8. If you take some other version training you're gonna get different info.
Cognos also has it's own manuals which I thought we made available too - I'll check on that and see if I am allowed to link them up here. Hang in there - there are resources out there - plenty, but the hard part is our data itself which is pretty comprehensive on Daptiv's native online help.
