Hello everyone,
I'm currently designing the structure of our new pg database, and I
have a question. In our current platform, addresses are stored in
several places, like this (in semicode):
company(name varchar(100), street varchar(100), state varchar(100))
employee(code int, street varchar(100), state varchar(100))
consultant(name varchar(50), street varchar(100), state varchar(100))
The colums street and state (and a lot more in real life) are the same.
My idea for the new db was someting like this:
company(name varchar(100))
employee(code int)
consultant(name varchar(50))
address(ref_oid OID, street varchar(100), state varchar(100))
In this way, I can store all the addresses together and find them with.
SELECT * WHERE addres.ref_oid = company.oid;
Sort of the same manner as the storeage of BLOBs. Is this approach
common practice? Is it safe? I know I have to make backups with the
OIDs etc., but besides that, any more pitfalls?
TIA!
