BitStream Indexes

If a large number of reports are to be created, the database is large, and/or you often need to filter for a particular question, then you can index the BitStream files. This will flag specified rows in the database, thereby reducing search times and improving performance.

You can index the BitStream file for Interview_start, Interview_end, status, single and multi questions.

To create a BitStream Index:

1. In Forsta Authoring, go to the Reporting > BitStream Indexes menu command .

4. Create the BitStream files (go to the Reportal > Create Reportal BitStream Files menu command).

A task pane opens, indicating the status of the task. Here you can set the task to re-occur if you wish to update the file at regular intervals. On completion, the file will be indexed as specified.
