Info

The SAP HANA database has its own scripting language named SQLScript. The motivation for SQLScript is to embed data-intensive application logic into the database. Classical applications tend to offload only very limited functionality into the database using SQL. This results in extensive copying of data from and to the database, and in programs that slowly iterate over huge data loops and are hard to optimize and parallelize. SQLScript is based on side-effect free functions that operate on tables using SQL queries for set processing, and is therefore parallelizable over multiple processors. In addition to SQLScript, SAP HANA supports a framework for the installation of specialized and optimized functional libraries, which are tightly integrated with different data engines of the index server. Two of these functional libraries are the SAP HANA Business Function Library (BFL) and the SAP HANA Predictive Analytics Library (PAL). BFL and PAL functions can be called directly from within SQLScript. SAP HANA also supports the development of programs written in the popular statistics language R. SQL and SQLScript are implemented using a common infrastructure of built-in data engine functions that have access to various meta definitions, such as definitions of relational tables, columns, views, and indexes, and definitions of SQLScript procedures. This metadata is stored in one common catalog. The database persistence layer is responsible for durability and atomicity of transactions. It ensures that the database can be restored to the most recent committed state after a restart and that transactions are either completely executed or completely undone. The index server uses the preprocessor server for analyzing text data and extracting the information on which the text search capabilities are based. 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 statistics server collects information about status, performance and resource consumption from the other servers in the system. Monitoring clients, such as the SAP HANA studio, access the statistics server to get the status of various alert monitors. The statistics server also provides a history of measurement data for further analysis.

The following illustrates such applications using the common Model-View-Controller (MVC) development architecture. 12 P U B L I C © 2012 SAP AG. All rights reserved. SAP HANA Developer Guide SAP HANA
SAP HANA greatly extends the traditional database server role. SAP HANA functions as a comprehensive platform for the development and execution of native data-intensive applications that run efficiently in SAP HANA, taking advantage of its in-memory architecture and parallel execution capabilities. By restructuring your application in this way, not only do you gain from the increased performance due to the integration with the data source, you can effectively eliminate the overhead of the middle-tier between the userinterface (the view) and the data-intensive control logic, as shown in the following figure. In support of this data-integrated application paradigm, SAP HANA Extended Application Services provides a comprehensive set of embedded services that provide end-to-end support for Web-based applications. This includes a lightweight web server, configurable OData support, server-side JS execution and, of course, full access to SQL and SQLScript. These SAP HANA Extended Application Services are provided by the SAP HANA XS server, which provides lightweight application services that are fully integrated into SAP HANA. It allows clients to access the SAP HANA system via HTTP. Controller applications can run completely natively on SAP HANA, without the need for an additional external application server.The following shows the SAP HANA XS server as part of the SAP HANA system.
