Events with workshops

[Phil]

I have an events database that I now need to add workshops, the basic
structure of the tables is

Events:
---------
EventID

Attendee:
-------------
AttendeeID

Registration:
--------------
RegistrationID
EventID
AttendeeId

the real world situation is that some events we run have workshops, normally
the group will split into smaller groups and attend one of the sessions

e.g.
Bereavment
MCA
Cancer

Each event may have more than one workshop in a day, one workshop or none at
all. I have no idea how to design the table structure, do I need seperate
tables for Workshops, sessions. Any advice would be greatly accepted. If
you need any more info let me know

Thanks

Phil

It sounds like you are saying one Event can have zero, one, or many
Workshops, and that Attendees are registering for Workshops rather than
Events.

If you add a Workshop table, then use WorkshopID in your trelRegistration
table, would that do it?

Hi Jeff

Thanks for your reply, you have it correct with the workshops, although the
attendees are first registered on an event and then chose which workshop they
want to attend. I have added a workshop table and did use a field in the
registration table to store what workshop they want, the problem is that
means they can only have one workshop for each course (unless I am missing
something as they only have one registration record for each course). The
other issue I have is that if an event has two workshops they may be
different workshops

e.g
am
Lung cancer
clorectal cancer

pm
breast cancer
kidney cancer

how do i account for that?

Hope you can help

We might be focusing to narrowly on 'tables' and not enough on the entities
and relationships. The tables will follow if you've laid out (usually
pencil/paper) the entity/relationship diagrams.

It sounds like you are saying:
* one person can register for one-to-many events
* one event can have one-to-many workshops
* one workshop can have one-to-many topics
* one person can register for one-to-many topics

Does this match your situation?

Yes thats right, my existing database already handle bookings for multiple
events, I am really struggling to add workshops to it, I thought I had it
until we ran an event with two workshops

Thanks

If my proposed description matches what you are working with, then you'll
want to consider a table structure that allows for each of those entities
(person, event, workshop, topic) AND another table (or more than one) that
lets you relate these (e.g., Registration).

Thanks again for your help, please correct me if I am wrong but I think you
might have relesaed my brain block. I already have Attendees, Registration,
Events, tables,
If I had a workshops table, and topics table along with a Workshops
registration table to allow registration of Attendees to a workshop, I think
I can see how this can work (I have a diagram in front of me that looks like
it will work). Thanks
