Unlike conventional applications it carries out analysis of large amounts of data at a significantly higher performance. SAP HANA runs on different certified hardware systems and can also be virtualized.

SAP HANA was launched in 2008 in cooperation with the Hasso Plattner Institute and Stanford University. The aim was to enable real-time analysis of large amounts of data.

When you reach by filing a reduction in the volume of data you need less memory. A SAP Business Suite system that meets the requirements to run on a SAP HANA DB called “HANA ready”.

Database migration and optimization – the migration to the SAP HANA Technically, a simple database migration, similar to a change from MS SQL Server DB to MAX. The entire database content is exported and re-imported to the new HANA database. Then, the application tests must be done. To use the HANA technology and fully exploit the potential of in-memory, targeted analysis must track down to opportunities for optimization. It is checked that database operations can be moved from the ABAP layer into the database layer to take advantage of the real-time capability (Push-down).

What is SAP HANA Studio?

SAP HANA Studio – For development and database administration, the Eclipse-based SAP HANA Studio is used. The HANA database can be accessed through the programming languages ABAP and Java, as well as ODBC. Using the ODBC interface compatible language can be accessed at the database with any other ODBC.

The SAP HANA Developer Studio supports the entire life cycle of application development. With SAP HANA Developer Studio SQL scripts and views can be created via the Extended Application Services (XS) SQL. In addition, a custom logic on SAP HANA server can be implemented. About HTML5, JavaScript and the SAP UI development toolkit for HTML5 adapted to HANA applications are created. SAP developers will need to have in the future ABAP, HANA and Eclipse skills.
