3. The Architecture of DBMS can be seen as either single tier or multiple tiers. 1-tier Architecture 2-tier Architecture 3-tier Architecture N-tier Architecture

4. 1-tier Architecture One-tier Architecture involves putting all of the required components for a software application or technology on a single server or platform.

5. 2-tier Architecture The application is partition into a component that resides at a client machine which invokes the database system functionally at the server through query language statements.

6. 3-tier Architecture The client machine does not contain any direct database calls instead application server communicate through a forms interface, the actions are carried out in the application server.

7. N-tier Architecture N-tier Architecture would involves dividing an application into three different tiers. These would be the The Logic tier The Presentation tier The data tier
