What are the three layers in SAP R/3?

• A. Database, Security, Presentation
• B. Database, Application, Network
• C. Database, Application, Presentation
• D. Database, Security, Network

Answer: (C)

In SAP R/3, the three layers refer specifically to the architecture that organizes how data, processes, and user interfaces interact within the system. The correct answer points to the Database, Application, and Presentation layers. The Database layer is responsible for data storage and management. It includes all the data that the SAP applications use and maintain. This layer ensures that data is consistently stored and can be retrieved as needed by the applications. The Application layer is where the business logic and processing take place. In this layer, various modules of SAP R/3 handle different business processes, from finance to supply chain management. It serves as the intermediary between the data stored in the database and the user interfaces that individuals interact with. The Presentation layer is the user interface part of SAP R/3. It is what end-users interact with, allowing them to input data, generate reports, and execute transactions. This layer presents data to users in a way that is easy to understand and interact with, often through graphical interfaces. Understanding these three layers is crucial for comprehending how SAP R/3 operates as an integrated enterprise resource planning system. Each layer plays an integral role in ensuring that business operations run smoothly and efficiently.
