Duplicate Customers/Accounts

Recommended Posts

Has anyone tried to tackle the "fuzzy" logic of trying to work out if someone has already registered with a site?

 

I know osC already checks email address but that is not enough.

 

You could also check the person's name and their address and even telephone numbers - all of which if they matched an existing account could indicate this was the same person registering again. But it is not fool proof.

 

Does anyone have any suggestions?

Not bothering would be great but a client wants it.

 

It is an inexact science but it is a typical routine that many systems use.

 

Anyone have any thoughts?

Give me the business rules, and I'll write the function.

NOTE: As of Oct 2006, I'm not as active in this forum as I used to be, but I still work with osC quite a bit.

If you have a question about any of my posts here, your best bet is to contact me though either Email or PM in my profile, and I'll be happy to help.

I would get the client to define the business rules for detecting duplicate customers, then implement those.

 

That way if it doesnt work the way they expect they only have themselves to blame.
