There are three different application types delivered with SAP Fiori. They are Transactional apps, Analytical apps, and Fact Sheets.
These apps run best on HANA, but can also run with any database.
These are purely analytical apps that will run only on HANA following the HANA Live (2-tier) architecture and using virtual data models (VDM). Typical representatives are Smart Business KPI Cockpits but also include other analytical, predictive, and planning applications. These apps are not ported to any other database (AnyDB). They either use Smart Business KPI Framework or HANA Live and XS OData.
Fact sheet apps run on HANA and the ABAP stack. These scenarios are not ported to any other databases (AnyDB).
