Two tier architecture :
Client server application. Client acts as Front End
and Server acts as Back end (databases).
Here where client make a request to the server where
the query evaluated in the server and returns the request
given by client .where here all the query evaluated in the
server side .
Three tier Architecture :
Three tier architecture means N tier architecture
1. Presentation Layer
2. Business Layer/ Middle Layer(tier)
3. Database Layer.
where here client make a request to server through
presentation layer to get some data the query is evaluated
in business layer and the data is retrieved from the
database layer(all the complicated work done in middle layer
) . Database layer is responsible for all the connections
between the server .so the accessing through database make
easier through 3tier architecture
