What is the difference between pre-generated and on-demand reports?

The differences between running pre-generated and on-demand reporting with respect to Firewall Suite:

The scheduler is an independent program.
The user chooses the report range for the profile and the type of report.
Firewall Suite parses the log files.
Firewall Suite then sessionizes the data.
If the user has selected to use the FastTrends database, the database is then populated. If FastTrends is not being used then no other databases are involved.
At this point in the process, pre-generated or on-demand reporting comes into play.
Pre-generated reporting means using the scheduler to run a report of a selected range. The report is generated in its entirety, whether it is HTML, Microsoft Word, Excel or ASCII text. The scheduler creates the report instead of the user clicking on the "start" button.

On-demand reporting means that the user selects a particular profile and then clicks the "Report" button. The type of report is then selected as well as the report range. The user then clicks "Start" and the report is generated in its entirety, whether HTML, Microsoft Word, Excel or ASCII text. No disk space is saved.

On-demand can be translated to mean a user can generate a report with any time range. The better term that should be used when dealing with these products is "Targeted Reporting."
