My boss is trying to get a custom database built for his companies.
We are working with a programmer and writing up the agreement.

What has us both kind of stumped is...
my boss wants full ownership rights to this database. The database and website will be hosted on our server.
The programmer wants an extra 40% for us to have this ownership.

I don't understand why we would not have ownership rights to the database when we paid 'Joe' to design it, using our software and server.
Why should we have to pay more?
We don't really understand.
Could someone please clarify why a freelance programmer would want full rights over another companies database?
