What is difference between SAP ECC, HANA and S4 HANA?

Hello Everyone,

The maximum critical distinction among S/4HANA and ECC is the database they use. While ECC runs on third-birthday birthday celebration database structures which includes Oracle, S/4HANA is based at the SAP in-reminiscence database. That method decrease IT costs, higher stability, and much less disruption from destiny SAP upgrades.

So this the actual difference from my point of view.
