In addition, some versions of Delphi include a Decision Cube category on the Tool Palette. It contains six components that let you perform data analysis and cross-tabulations on data when building decision support applications. For more information... more 
The Data Controls category of the Tool Palette provides a set of data-aware controls that represent data from fields in a database record, and can permit users to edit that data and post changes back to the database. Using data-aware controls, you can build your database application's user interface (UI) so that information is visible and accessible to users. For more information on data-aware controls see Using data controls.
In addition to the basic data controls, you may also want to introduce other elements into your user interface:
If you want to let your users print database information from the datasets in your application, you can use Rave Reports, as described in Creating reports with Rave Reports.
