What is SAP HANA?
SAP HANA is an in-memory data platform that is deployable as an on-premise appliance, or in the cloud. It is a revolutionary platform that's best suited for performing real-time analytics, and developing and deploying real-time applications.
HANA also includes a programming component that allows a company's IT department to create and run customized application programs on top of HANA, as well as a suite of predictive, spatial and text analytics libraries across multiple data sources. Because HANA can run in parallel to a source SAP ERP application, analysts can access real-time operational and transactional data and not have to wait for a daily or weekly report to run.

All databases stores and retrieves the data from DISK..but HANA Database stores and retrieves the data faster from RAM instead of Disk..so execution and retrieved time is more faster than other databases
