The two-tier application programming model was developed to enhance the file server application programming model. As compared with the file server application programming model, the two-tier application programming model provides you with improved usability, scalability, and flexibility of applications.
In Two-Tier model, you will have two seperate layers namely Client & Server.
The applications developed using the two-tier application
programming model have a user-friendly interface.
These applications can support only a few users and
allow data to be shared within a homogeneous environment.
Example of the Model
The various tiers in a two-tier architecture are separated from each other by physical boundaries. These physical boundaries can be machine boundaries, process boundaries, or corporate boundaries. |
