Cognos8 Express authoring mode

One of the best features of Cognos is adhoc reporting, users can get any data without the help of professional report developer using query studio.
There was a limitation with query studio, users were not able to use advance reporting features.
Now in Cognos 8 users are able to use advance features as well because Cognos 8 introduced Express authoring mode.
The Express authoring mode provides a simplified and focused Report Studio interface.It is designed for non-technical users to create traditional financial and management statement reports.Note :Express authoring mode allows access only to dimensionally-modeled data and uses a member-oriented data tree.This authoring mode allows you to see live data and supports only crosstab reports.It contains a subset of the features available in the Professional authoring mode.When you are in the Express authoring mode, if you open a report that was authored in the Professional authoring mode, you can see but cannot modify objects that can be inserted only in the Professional authoring mode, such as charts, maps, and lists.Then what are you waiting for? Just grant the access of Express authoring mode to your users and let them get benefit of using Cognos8 as their information management tool.
