UDINA BTPWebshop 2.0
The Webshop 2.0 of the City of Zurich is a Multi Cloud Omnichannel E-Commerce solution, based on the SAP Business Technology Platform (BTP) and Microsoft Azure.
Omnichannel E-Commerce
Putting a successful omnichannel strategy into practice first requires adapting the organizational structure in order to operate and expand sales channels across departments and thus avoid information silos.
The new webshop allows central access to cross-departmental information, with the option of integrating additional channels in the future.
Cross-channel integration allows a business process to start on a device such as a smart phone and later be continued on the desktop. All process-relevant information is retained user-specifically and can be used across devices.
Functionalities such as the Excel export of the product catalog allow a simple change of media. This means that the order data can be further processed offline. The further processing then takes place later by importing the article into the shopping cart (file upload or copy and paste).
