SAP NetWeaver Architecture

SAP NetWeaver architecture is built as a multi-layered technology stack that integrates application services, data management, and user access into a unified framework. At its heart, SAP NetWeaver follows a three-tier architecture that separates responsibilities into distinct layers. This separation makes the system easier to manage, scale, and secure.

• Presentation layer. This is the user interface tier. It can be the classic SAP GUI, a web browser, or newer clients like SAP Business Client. Its sole function is rendering the UI and forwarding user requests.
• Application layer. This is the “engine room” where all the business logic runs. It uses ABAP and Java application servers to process requests, carry out calculations, and enforce business rules. It sits between the user interface and the database, ensuring smooth communication. To handle large workloads, it also manages load balancing and failover for reliability.
• Database layer. This tier provides persistent storage of business data. SAP NetWeaver is database-agnostic, supporting SAP HANA, Oracle, SQL Server, IBM DB2, and others. The database ensures ACID compliance, transaction consistency, and query optimization. It is accessed exclusively by the application servers.

Beyond this three-tier core, NetWeaver includes additional services that expand its role:

• Integration services. Through SAP Process Integration (PI/PO), NetWeaver acts as middleware, connecting SAP systems with non-SAP systems. It transforms messages, routes data, and ensures that different applications can “speak” to each other.
• Portal and collaboration services. Through SAP Enterprise Portal, NetWeaver provides a unified portal where employees can access applications, documents, and reports in one place. It also enables workflow, document management, and team collaboration.
• Security and user management. Authentication, authorization, and role management are handled here. Features like single sign-on (SSO) and directory integration ensure secure and seamless access.
• Development and customization tools. Developers use ABAP Workbench and NetWeaver Developer Studio to build or extend applications. This makes it possible to tailor solutions to unique business needs while supporting modern service-oriented architecture (SOA).

The SAP NetWeaver architecture is designed to be modular and service-oriented, meaning organizations can adopt specific components as needed while maintaining a scalable and interoperable IT environment. This layered design not only simplifies system administration but also ensures high availability, extensibility, and compatibility across heterogeneous infrastructures.
