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

[Rachel Luis]

Is S4/HANA another version of SAP HANA? Or, are both of these the derivation of the same technology?

1. SAP ECC: To start with, SAP ECC (ERP central component) is basically an enterprise suite that consists of ERP modules comprising of human resources, warehousing, finance and also logistics. To be more exact, ECC overlaps with SAP ERP and SAP R/3. This is what usually causes confusion between the three.
2. SAP HANA: As mentioned before, SAP HANA is the backbone that typically runs the SAP landscape. Its core feature is RDBMS (relational database management system) which is an innovative column-based system. SAP HANA itself does not take the responsibility of the task management of a business, and it usually accommodates any type of data.
3. SAP S/4 HANA: SAP S/4 HANA was launched in 2015 and is SAP’s next-generation business suite, which is specially designed to run only on SAP HANA. S/4 HANA is basically SAP business suite 4 SAP HANA. After R/3, it is the fourth business suite version. As it is solely compatible with SAP HANA, it has replaced the old SAP ECC ERP system with SAP HANA. Still, it is based on its successor and treats it as its core technology.

A standard 3 tier application consists of a database, storing data (obviously), an application server running business logic and the business logic and. The presentation layer.

Considering S/4 HANA as the whole solution (consisting out of all technical components) SAP HANA as the underlying database (not the full story, since SAP HANA has evolved more and more into a platform containing libraries for more efficient calculation and presentation) and SAP ECC (ECC stands for enterprise core component) as the technical core (app server) of the SAP versions before S/4 HANA. The difference: ECC could deal with different database platforms underneath (Oracle, DB/2, MS SQL and of course HANA). S/4 HANA only runs on top of SAP HANA.
