Refreshing web report data

As a web developer, you must decide if you want to allow users to refresh report data themselves, or if you want to control how and how often they can refresh report data. Refreshing report data allows users to retrieve information that is up-to-date. However, web sites with several users refreshing report data can result in network and system slow downs since every refresh requires connecting to a database and gathering data. As well, frequent refreshes of report data limits report caching capabilities of the Cache Server. Every time the report is refreshed, any cached version of that report becomes obsolete.

The following sections outline ways that you can limit or even disable the user's capability for refreshing and suggest other means for keeping up-to-date data in reports.

• Generating reports with saved data
• Scheduling reports
• Disabling the Refresh button
