Regarding Database Design
Date: Sun, 10 May 2009 22:37:45 -0700 (PDT)
Please accept my apologies if this query is out of context of the discussions in this forum.
I've with me a proposed database design which is not normalized fully. There are some other tables that we plan to denormalize. The targeted database platform is Oracle Database 10g Release 2.
For ex:- We have a table called user_groups which links the users and the groups table. But now we are thinking to eliminate this table and have a group_ids column storing comma separated values of groups ids from the groups table instead.
The records will look like -
group_id group_name 1 Admin 2 Operator 3 Power User
user_id user_name group_ids 1 User1 1,3 2 User2 2,3
The targeted database will be a typical OLTP system. Please suggest if this approach to database design has any fundamental flaws.
Thanks in advance
