Hi,
I'm a beginner too, but without a table FK (relation) how you make a join
statements ? Do you normalize your tables ?
The relation model is concerned with logical maters only, not physical
matters. It addresses three aspects of data, data stucture (object) data
integrity, and data manipulation.
The Object (Tables),
Integrity portion has to do with PK and FK
Data manipulation (SELECT, JOIN etc)
In addition I think with the Normalized database you will have smaller
database and easy to maintain (base on object).

Hi all:
We have a situation where are no relationships are
defined at the database level. i.e no foreign keys
constraints have established at the Database. The
application is still at the Development Stage.
Everything is controlled at the application level.
I as the DBA appose this design for Data security and
also cannot reverse engineer from the tables into
Designer.
Can you please share you pros / Cons.
Thanks
