Introduction to SAP HANA
THE HANA architecture is a revolution in columnar database application has been brought about by SAP HANA. It combines the features of in-memory computing and columnar database management system (DBMS), a duo that tremendously enhances speed of operation when performing real-time analysis or running real-time applications. In-memory processing fundamentally utilizes the system’s RAM (main memory) to store data, instead of using disk storage. A columnar DBMS boosts system performance and speed when working with aggregates, by reading only the data that is required to satisfactorily fulfill a query, through effective compression of similar columnar data. This technology effectively deploying this combination, thus becomes one of the best suited tools for data warehousing applications.

Companies often need to work with aggregates, i.e., huge databases of different types and from different sources and require answers to complex queries out of the data. SAP HANA proves to be one of fastest and most efficient tools in such a situation. The reason is that it is the only DMBS that is exceptionally good in handling both analytical workload (with complex queries, involving aggregates) as well as transactional workload (data typically having a number of short, online transactions) processing. There are various DBMS which are good at handling either online transactional processing (OLTP) or analytical processing (OLAP) but SAP HANA stands out of the crowd to serve both. SAP HANA consists of major components like the HANA Studio which is an Eclipse based IDE for managing HANA database, creating and managing user authorization and working with data models. HANA also consists of the HANA Cloud which is used to create and test HANA-based cloud applications.
