This is to do with how you access databases.  1 Tier is when the database system is using the local BDE, 2 Tier is when you use something like Oracle or SQL Server, 3 tier is when you use a Client application/Server application (as well as MIDAS or the like) and the RDBMS such as SQL Server...thats a *very* informal comment (but worth 5 ;)

The meaning is for people to do faster and more advanced calculations on the server-side. A DBMS is really effient at data storage, but you could actually have all business rules of a company handled by the server instead of the client's which tends to be more unstable and critical.
This is the main reason for making a system multi-tiered - I think :-) any other suggestions on this folkes...

Another poin-of-view is MIDAS approach.

A multi-tier application can be divided in Database server (one level), an application server that is an executable that uses one of the distributed object standard, like CORBA, COM, MTS and the third level the user interface that uses TClientDataSet. This third level doesn't require BDE (it's a thin client). It changes data with the data module in the application server using one of those protocols.
