Dear all,
This is a general design question.
Over the years, I've been creating an oracle database storing financial
data; about 60 tables.
I consequently designed all tables this way:
So far I think this is a common approach. The main advantage is you can change the "logic key", without the need to do any changes in detail tables.
However, if you look into the detail tables, you see a bunch of integer
numbers which are completely meaniningless unless you join them with their
master tables.
Also if you want to insert or retrieve data, you always have to lookup or to
join with other tables.
I currently ask myself if using the integer primary keys is really worth the
effort.
So what about replacing the integer keys by "meaningful" keys and also
storing these keys in the detail tables?
I know, if a key needs to be changed, then detail tables need to be
changed, too.
But on the other side a lot of trouble when handling table data will be
avoided.
What's your opinion about this topic?
Do you have any experiences with databases in these two design apporaches?
Best regards
