SAP / SAP Beginner (0 to 2 yrs) Interview questions
What are the advantages of a 3-tier architecture?
Splitting a system into presentation, application, and database layers brings several practical benefits over a simpler, tightly-coupled design.
- Independent scalability — add more application servers to handle more users, without touching the database or presentation layers.
- Centralized business logic — logic lives on the application server, not scattered across individual user machines, making it easier to maintain and update consistently.
- Improved security — end-user devices never connect directly to the database, reducing the attack surface for sensitive data.
- Flexibility in deployment — each layer can run on separate hardware suited to its specific workload (e.g. powerful database hardware, separate from application processing hardware).
This separation of concerns is a big part of why SAP systems can scale from small installations to supporting tens of thousands of concurrent users across large global enterprises.
What is one key advantage of separating the application layer from the database layer?
How does the 3-tier architecture improve security compared to a design without layers?
