Analyzing Data

From InterBase

Go Up to Designing the User Interface


Some database applications do not present database information directly to the user. Instead, they analyze and summarize information from databases so that users can draw conclusions from the data.

The TDBChart component on the Data Controls page of the Tool Palette lets you present database information in a graphical format that enables users to quickly grasp the import of database information.

Also, some versions of Delphi include a Decision Cube page 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 about using the Decision Cube components, see “Using decision support components” in the Delphi Developer’s Guide.

If you want to build your components that display data summaries based on various grouping criteria, you can use maintained aggregates with a client dataset. For more information about using maintained aggregates, see Using maintained aggregates in the Creating and using a client dataset chapter of the Delphi Developer’s Guide.
