When I search for SAP HANA, it says it's a column-oriented in-memory analytical RDBMS; is that outdated info? Where is the actual data stored if this is in-memo

- majewsky 6y agoFrom what I know, HANA also keeps a copy on disk at all times. The "in-memory" label is valid because a full copy of all database contents is held in memory, and all reads are performed on that copy. Disclosure: I work at SAP, but neither on HANA nor on any part of the "SAP system". (I'm in the cloud infrastructure unit.)
