Database design help needed please!
Hey guys, I'm new to this forum so firstly hi, it's great to find such great place!
So my issue is I'm trying to design a database system for a website I intend to implement, its for booking and viewing appointments, I've done a lot of work in terms of what I want it to do and have the knowledge to do it, I just want some input into my database design.
Okay so I have 3 tables, membership, availability and appointments, heres what they look like so far:
The idea is that a member registers (details held in membership table), then they then define their availability (details held in availability table). Now, they may book appointments with other members and other members may book appointments with them, provided that the time they book is available according to the availability of the member they are trying to book with. (Sorry if thats a bit confusing)
Anywho, my question is, am I missing anything that is necessary? or is there anything redundant in there that is not needed?
Thanks for any advice or pointers, I'm kind of new to databases!

For one pointer I see right off the bat is that you should not have identical named fields in your tables. You should preface them like the availability table field "DATE" could be named AV_DATE, and the Appointment table field AP_DATE. This would be internal. If you have forms set up your lables can still read "DATE" but the field name would be AV_DATE or AP_DATE. This way if you run queries the database will error seeing DATE as ambiguous name not knowing which table to use.
