IBM Cognos Query Studio
IBM Query Studio is a very basic web-based ad hoc query & reporting tool. It is used to create simple list or crosstab reports in order to quickly consult the data. It is supposed to be a way for end-users to self-service themselves for data that is not accessible through pre-build reporting (through ReportStudio). It offers more limited functionality then Report Studio, making it easier to use, and is accessible via the Cognos Connection portal.
