• Column oriented storage in SAP HANA

  All column oriented tables are also made available in row oriented form by SAP HANA. This makes it possible to choose the best way to access the data: via the row store or the column store. Changes to the data require extra work to update both the row and the column store.

• SAP HANA database manager - introduction

  The key challenge of designing contemporary database management software: on large data sets it has to work well for both row and column oriented operations. An ERP-application requests many, simple, row oriented read and write operations: request a row, update and store it. An analytics-application requests fewer operations, mostly reading, but on larger data sets.

The column store suits Online Analytical Processing (OLAP, like business intelligence) much better.
