Chapter 3 Design Explore and Elaborate Requirements Design Prototype Validation Delivery Figure 3-4. Platform design phases Design of Various Layers A DXP is a flexible platform that has the capabilities of rapid development and innovations. A DXP has a web application with a content management system (CMS) and provides features such as marketing, targeting, personalization, commerce, etc. You can build web applications, mobile applications, chatbots, AR, VR, AI, and enterprise search engine components for devices such as tablets, mobile, desktop, and IoT, as shown in the presentation layer in Figure 3-5. These applications on different devices are connected through the integration layer; you can choose architecture type such as microservices or monolithic application, and services built are exposed using an ESB and API gateway. Business logic is implemented while accessing data from the data access layer and exposed using the integration layer, as shown in the figure. The middleware layer is responsible for implementing NFRs such as reliability, security, accessibility, and scalability, etc. 70
