Reports display static and dynamic information. Dynamic information is something that changes through a report - values from a database(actual report data) or service information(such as current user name or page numbers). Static information is text or images that doesn't change through the report, and doesn't depend on the current computer. Such information can be printed only once (e.g. in a report header), can repeat on each page (e.g. in a page header) or can repeat with every entry in your report (a label describing your data).
