Scheduled Job

Just rand across this article:

http://www.aspfaq.com/show.asp?id=2143, which led to this article on using a
SQL Server job: http://www.aspfaq.com/show.asp?id=2403

Here's my question: I have an intranet app which tracks tickets for tech
support. The boss wants it so that, depending on the severity of the ticket,
we go into the DB and check every 15 minutes or so to see if the ticket is
being handled. If no activity is detected in an accepted amount of time,
then an email gets sent automatically to certain managers,
The first article cited above gives 4 options, and the last two aren't
possibilities in my case. I'm leaning toward option 2, which is the SQL
job, but will take advice.
