Hi,

I'm looking for a "best practices" way of creating tables to store both
one time and regularly repeating events.  These are classes, so for the
most part the have a regularly recurring time, but we do have some one
off events.  For example, let's say the following:

Class-A Mon,Wed,Fri 8-9 from August 20th-December 5th
Class-B Mon,Wed,Fri 9:10-10:10 from August 20th-December 5th
Class-C Tues,Thurs 10:30-12 from August 20th-December 5th
Class-D Wed,Thurs,Friday  1-2 from August 20th-December 5th
Class-E Tues,Thurs 8-9 from September 15th-January 15th
Event-F Thursday, November 8th, 12:30-3

I could have 1 table that had Name, Start_time, Stop_time and have one
entry for every single class and event.  That is a simple way to design
the table, but it seems like there's lots of needless duplication.
There are going to be 50+ entries for Class-A, one for each day it
meets.

It seems like there ought to be a way to use something like the ical
recurring event format to set things up so that there's 1 entry for each
event and that includes the recurrence.

The only other way I could think of to do it would be to duplicate the
cron format and have a table like this:

Name, start_day, start_datetime, stop_day, stop_datetime, 

'Class-A', '1,3,5','2007-08-20 08:00:00', '2007-12-05 09:00:00'
'Class-D', '3,4,5','2007-08-20 13:00:00', '2007-12-05 14:00:00'

And then parse everything, but that seems resource intensive too.

Any suggestions for the best way to handle this?

Thanks,

Bob
