Building blocks of an application on SAP BTP
Service
Data model, services, authorizations and interfaces to the connected systems.
Data models and OData services with CAP, business logic in the services and as SQLScript in the database.
Data storage in SAP HANA Cloud with HDI containers.
User interfaces with SAP Fiori Elements on the OData services, role model with XSUAA, aligned with the authorization concept of the business side.
Connection to SAP S/4HANA via released APIs and OData services.
Automated tests, code reviews and release management with SAP Cloud ALM.
Context
SAP BTP fits when an extension is to run alongside the ERP system and the core of the system stays unchanged (clean core). It also fits when a custom development is moved off an on-premise system or when a product for several customers is built on a shared core.
The runtime is Cloud Foundry or Kyma. Which of the two is chosen depends on operations and on the skills available in the company; we clarify this during the design phase.
