1 Types of SAP HANA Models This chapter provides an overview of the different models that can be created in SAP HANA. For each model type, the chapter defines the model in question, outlines the criteria for choosing it, and explains its benefits. 1.1 SAP HANA Database Engine Architecture SAP HANA is an in-memory technology platform that is deployable as an appliance or in the cloud. Its core is the SAP HANA database, which is built for high performance applications. It makes full use of the main memory and processing power provided by modern hardware. As relevant data is kept in main memory, read operations can run in main memory. SAP HANA is also designed to make full use of multi-core CPUs by parallelization of execution.

The XS server also hosts several system services, for example for data replication, and for analytical queries and search queries over HTTP. Several web-based tools included with SAP HANA are also running on XS, for example for development, system administration, and life cycle management. The name server owns the information about the topology of a SAP HANA system. In a distributed system, the name server knows where the components are running and which data is located on which server. The SAP HANA studio is both development environment and administration tool. Administrators can use the SAP HANA studio for example to start and stop servers, to monitor the system, to configure system settings and to manage users and authorizations. As shown in figure 4, the SAP HANA connects to the SAP HANA servers via SQL. Developers can use the SAP HANA studio to create content such as data models, modeled views or procedures. These development artifacts are stored in the SAP HANA repository. The SAP HANA studio is based on the Eclipse platform. In addition to SAP HANA studio, there are also web-based tools for administration and development. The server side parts of these tools are system applications that run in the XS server. Web-based development tools can be used to perform most development tasks in a browser. Web-based XS
