MySQL：这套自定义成员记录应该形成一个单独的数据库，一个新表还是仅一个新列？

Question

I have two MySQL databases,one from a membership script (MS) and one from a forum script (FS).

MS is like this:

___________________________________________________  

useremail    |      membergroups | oranges | apples | pears |... (and 30 more columns)  
_______________________________________________  
jill@jill.com | A,B,C     | 1     |  0  |   1  |...... (and 30 more values)
________________________________________________  


and FS is like this:


- - - - -- - - - -- - - -- - - - - -- - - -

USER_ID  | USERNAME | EMAIL     |    GROUPTYPE  |
- - - - - - - - - - - - - - - - - - - - -- - - -
2289   | jill     | jill@jill.com | gold  |
---------------------------------------------

So:

1) The two member tables are of course very different.
2) The MS member table has many, many data columns.

Goals:
1) I'd like to draw on the many data in MS in whatever membership script/forum combo I wind up ultimately using. 2) I want to establish a Single Sign-On, so the user only needs to login once for both systems to operate.

Question: Would it be best to

a) store the MS data in the existing MS DB, and just have the FS DB query it;
b) add a new table to the FS DB, and add the old MS data to the new FS table, so that are now two distinct tables carrying member data in the same DB;
c) add the MS data to newly created columns in the FS DB;
d) do something else that I haven't thought of.

My gut says "b" is the best choice, but since I've gotta hire someone to do this, I'll stackoverflow's insights over the promptings of my gut.

Answer 1

In my respect b is also best choice. I prefer you to go with it .
