HYRISE

Traditional databases are separated into ones for current data from the day-to-day business processes and ones for reporting and analytics. For fast moving businesses moving data from one silo to another is cumbersome and takes too much time. As a result the new data arriving in the reporting system is already old by the time it is loaded. HYRISE proposes a new way to solve this problem: It analyzes the query input and reorganizes the stored data in different dimensions.

In detail, HYRISE partitions the layout of the underlaying tables in a vertical and horizontal manner depending on the input to this layout management component. This optimization allows great speed improvements compared to traditional storage models.
