Executive Summary

The SAP HANA database is a relational database that has been optimized to leverage state-of-the-art hardware. It provides all of the SQL features of a standard relational database along with a featurerich set of analytical capabilities and an SAP-specific programming language for stored procedures called SQLScript. With these facilities, the SAP HANA database is capable of embedding application logic within the database itself. This allows complex queries to be executed directly inside the database, thus reducing the requirement of data transfer to and from the database. This enables SAP HANA-based applications to process vast amounts of data whilst operating in a responsive, real-time manner.
