Usage Summary Table

The summary table shows statistics for these variables:



Number of successful logons (connections) to the database.


A query submits a request for results to a database. A query is recorded when a user clicks Search on any page where it submits a database search. Clicking Search to go to another page in BIOSIS Previews does not record a query.

At the bottom of the table are two rows showing:

Total Use   Sum of the numbers in each column. This is the total use for the year.

Average Use   Average number (arithmetic mean) for each column. This is the average use for the year.

If you selected the option to Include IP Addresses and Token IDs on the select a report page, then the table will have an additional column with this heading: IP Address/Token ID. To the right of the IP Address or Token ID in the same row are usage statistics for that identifier. The date of usage is in the row above and to the left of the identifier.

For example, this report shows that on January 1, 2003, the person(s) using a computer whose IP address is 123.45.678 logged on 76 times and submitted 48 queries to the BIOSIS Previews:
