Just an idea...but instead of checking the database every minute. why don't
you check to database every 15 minutes or so. When you check the database,
capture the times that are 15 min to 1 hour ahead of the time you are
looking for and save it to active memory. Then iterate over the data you
have stored in active memory (maybe in a Vector) until you you find a match
and send out an alert. Repeat this process again and write over your old
store of memory. Sounds challenging.

Subject: Re: Reminders for web based Calendar
I have to give reminder to his email or a Mobile...so
I basically should be having a Calendar server running
which can keep track of all these reminders...
Lets take a case :
User wants a reminder on Wednesday 5.30 pm about
something....and he sets the reminder today....
so the Calendar server should be checking the database
..lets say every one minute
but that will be too much...so what are the other
techniques???
Please help...this is really urgent
