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.
Within Query Studio it is possible to filter, sort, suppress and group the data. You can perform calculations, change the format of data and insert charts. The list of charts is limited compared to the list of charts in Report Studio.
