I have 13 MySQL (linux-PHP) databases and growing
I They all have their own customers with login and address book information (telephone, address etc)
I want to have a system whereby the USER ID / ADDRESS etc gets shared between all the databases
or another way to look at it
if a NEW USER registers in store 1 then they can log on to store 1, store 2, store 3.....store 9999 without the need to Re-register in all the other stores
u can see the practicality of this !!!
