What is SAP HANA?

SAP HANA is an in-memory, Column-Oriented, Relational database management system developed and marketed by SAP AG.

HANA Stands for High Performane Analytic Appliance.



How does SAP HANA work? 
SAP HANA combines an ACID-compliant database with application services, high-speed analytics, and flexible data acquisition tools in a single, in-memory platform. As an in-memory database, SAP HANA stores and retrieves data used by applications. It can also act as a modern-day warehouse, integrating data from a wide variety of data sources with live transactional data to deliver up-to-date insights. Built-in application services support the development and deployment of new business apps that exploit data from the digital highway and leverage advanced data processing – text search and analytics, predictive analytics, spatial data processing, graph data processing, and streaming analytics – to deliver deeper insight from Big Data and the Internet of Things at unprecedented speed.
