As long as people want to define all the terms here, I'd like to make really sure I understand.

Can't you say that client-server is one type of 2-tier or 3-tier architecture? If you have a 2- or 3-tier architecture, the and database server layer is processing SQL code to return a subset of data to the middle tier, isn't that what client-server means?

In other words, a client-server database is necessarily an n-tier architecture, whereas an n-tier architecture isn't necessarily client-server? Or IS IT?
