SAP FIORI Backend Development Odata FIORI Applications
SAP Fiori is a collection of design guidelines, user interfaces and apps that provide an intuitive and modern user experience for SAP applications. Fiori apps can be used on different platforms and devices and cover various business areas, such as finance, human resources, purchasing, sales and more.
In the back-end development process of Fiori applications
OData services play an important role in the back-end development process of Fiori applications. OData stands for “Open Data Protocol” and is a web-based protocol that makes it possible to easily exchange data via the HTTP protocol. OData services serve as an interface between the Fiori front-end application and the data sources and business logics behind it.
Here are some important points that are relevant in the context of SAP Fiori backend development and OData services:
To provide data and functions for Fiori applications, OData services must be developed. This includes the definition of entities (data models), the implementation of CRUD operations (Create, Read, Update, Delete) and the definition of business logics.
SAP Gateway is a technology that serves as a central element for the creation and provision of OData services. It enables the connection between the back-end systems and the Fiori front-end applications. Gateway provides functions such as routing, authorisation, error handling and service cataloguing.
When developing OData services, the data models must be defined according to the requirements of the Fiori applications. This includes the selection of relevant data sources, the definition of entities, attributes, relationships and annotations.
OData services allow data to be created, retrieved, updated and deleted. The implementation of these CRUD operations should take into account the business logics and validations to ensure the integrity of the data.
The OData services must be appropriately secured in order to control access to data and functions. Various security mechanisms are used here, such as the use of OAuth, authentication and authorisation mechanisms.
It is important to thoroughly test the developed OData services to ensure that they function correctly and deliver the expected results. Effective error handling and error logging is also required to quickly identify and fix problems.
Powerful and user-friendly applications
SAP Fiori backend development and the use of OData services enable companies to deliver powerful and user-friendly applications tailored to the specific needs of users.
