Re: Scheduling algorithms (Was: Testing if two lines or vectors intersect/overlap)

[Walt Nelson-4]

David,

I once did a 4D Web based scheduling app, and I came to the same conclusion you did: a "Master" record for the event, with an "Occurrence" record for each instance. The Master record has all the details, and the Occurrence record has the master I'd, occurrence I'd, date, and time.

So when the name (for example) of the event was changed, I didn't have to update a ton of Occurrence records, since that info was being displayed from the master event record.

a ton of details for each event that have not much to do with the
schedule itself.) I'm planning, from there, to build out every single
event.

Glad to hear you've been down this road and it works well enough. It
seems like the right way to go.

Thanks,
