Long time no see !
To improve access to Cognos information this site is up. Hopefully it will contain some info that you can use.
More information can be found at www.cogknowhow.com
Year 2008 to 2016 information was provided to www.cogknowhow.com as it is hard to find information at IBMs website.
Year 2016 and forward www.cogknowhow.com is run by https://motio.com… Then this site come up.
Year 2021 IBM push Cognos knowledge to partners, so now we include information about other things as well.
