=head2 execute ( [ object ] )
|
|
|
|
Analyze the passiveLog table, and generate the deltaLog table.
|
|
|
|
=head3 notes
|
|
|
|
If there is only 1 line in the table for a particular sessionId or
|
|
userId, no conclusions as to how long the user viewed a page can be
|
|
drawn from that. Similarly, the last entry in their browsing log
|
|
yields no data, since we require another entry in the passiveLog to
|
|
determine a delta.
