Analytics on Historical Data

Analytics on historical data
All enterprise data has a lifespan: depending on the application, a datum might be expected to be changed or updated in the future in many cases, in few cases, or never. In financial accounting, for example, all data that is not from the current year plus all open items from the previous year can be considered 'historic data', since they may no longer be changed.

In HANA, historical data is instantly available for analytical processing from solid state disk (SSD) drives. Only active data is required to reside in-memory permanently.
