There are huge differences between "Cognos TM1" & "Cognos 10 BI"!
Cognos TM1 is a (OLAP) multidimensional database which can be queried from Excel and the Web through "TM1 Web", "TM1 Executive Viewer" and "Cognos 10 BI". Within this database, you'll be able to create almost anykind of OLAP / Decisional application.
Cognos 10 BI is a web based reporting application. Users, depending on their rights (licence) will be able to run reports, schedule reports and/or create ad hoc analysis against relational and/or multidimensional databases. In order to do so, a logical layer has to be built using "Framework Manager". This logical layer is used to hide database complexity and to provide to the end users relevant information.
