Home -> Community -> Mailing Lists -> Oracle-L -> RE: Theory v Practice
Craig - I've seen large/busy databases run with RI handled outside the db.
Most common with package apps like Peoplesoft. They do that because they
want to run on many DBMSs and each handles RI differently. To reduce
development cost, they code once to the least common denominator. Thus no
RI in the db. Also opens the door to lots of problems that would be avoided
with RI in the db.
Not sure why you would elect to do such a thing with a homegrown app. Wouldn't be my first choice.
Even so, I'd say yes - the db is still more than an expensive filesystem. You still benefit from indexes and a query optimizer for performance; concurrent access to data; backup/recovery; etc...

The developers working on our new VB app are also responsible for
setting up the Oracle DB behind it. The app is for an order
entry/despatch/warehouse system with >5 million customers and >1000
orders per day. We have nearly 400 tables. They are not planning on
using primary keys/secondary keys, as they say they will handle all the
constraints via VB.
I only have a theoretical knowledge of database design, which says this
is very wrong. Is the Oracle system being used as anything more than an
expensive file system? In real world scenarios, is this a common
practice?
