# Reports

A report in JReport is not only a passive document used only for reading or viewing but also a business document that contains the predefined data. It is a form that typically contains data from many unrelated records or transactions.

JReport reports are usually composed of different components, with each component serving different purposes. They have the same functions as with general reports, but also include additional unique qualities.

In addition, the report templates in JReport use a flow layout model, which means paragraphs and components in the report body can flow from one page to another, maintaining their sequence.

This chapter details JReport reports in the following sections:

- What is flow layout?
- Creating a report
- Designing a report page
- Editing a report
- Previewing a report
- Making high-efficiency reports
