CHAPTER 5 Designing the Integration Layer After going through extensive UI concepts, now we look into the integration layer, which helps us to integrate with the DXP UI and further enhance DXP capabilities with a lean and flexible integration platform. Existing systems are integrated with the maintainable and scalable integration layer. The key features of the DXP integration layer are the following: • Various types of integration platform. • Architecture and frameworks used in integration layers. • Technology stack to develop integration layer. • Case study – banking experience platform. At the outset, we take into the picture the introduction and features of the DXP integration layer. DXP integration concepts help you make effective decisions on Web API (application program interface) management tools to integrate services with the DXP UI. According to the business requirement, the API management tool can be used and integrated with the DXP. Business requirements can help you to focus on understanding the basic requirements of the integration, for example, some requirements focus on portal and some on analytics services, so decisions should be made as per the requirement. © Shailesh Kumar Shivakumar, Sourabhh Sethii 2019 149 S.
