greetings all... I know this is more of a db question, but I'm hoping
that my fellow asp folk will take pitty on me and help me out.
If someone could provide me with some insight as to how I should break
up and normailze these tables I'd be most appreciative. I am
struggling with putting my own tables in order, although I do
understand the concepts of normaization.

Thanks

Here is where I see redundancy...

I will have handpieces that will belong to multiple systems. If I am
to only have indovidual handpieces in the handpieces table (primary key
is handpieceID), what table shoudl I create to repesnet the
relationship to systems.

Thanks

Because you're dealing with a many-to-many relationship (i.e. the most
complicated kind of relationship) sounds like you need a linker table
with systemID field and handpieceID field.
