Eric,

If I understand you correctly, you propose to encode user and group info as table names. That's a mistake. To use an RDBMS like MySQL effectively, you want to encode your information as rows of data in tables whose names and structures do not vary. May I suggest you read some of the tutorials listed at http://www.artfulsoftware.com/dbresources.html, and/or read http://www.artfulsoftware.com/mysqlbook/sampler/mysqled1ch01.pdf.

Not having done much database design in the past, I have what should be a fairly simple design question.

I usage of mySQL will revolve around a common group + user system. There
can be multiple groups and each group will contain some subset of users.

Each group will have a custom set of data whose values vary per user.

So basically a sample structure might look like this:
(some details intentionally left out)

Database

  Table_Group_A
    # of user columns

  Table_Group_A_UserX
    Column 1 Data
    Column 2 Data
    ...
    Column N Data

One probably incorrect thought on my part is that it would not be
necessary to store the usernames in Table_Group_A of those users who
belong to that group. But, thinking about it more, it seems like a good
idea. My original intent was to simply look for tables named
Table_Group_A_* and extract the username from the table name...

Does anyone have any recommends concerning this kind of design? I would
like to be able to lay things out in mySQL as cleanly as possible.
