Chapter 3 Design The patterns mentioned will help to build services and solve integration problems from End-point A (application A) to End-point B (application B). These patterns encapsulate the design knowledge; hence, irrespective of any integration technology, it will help to solve the integration problem. We look at the following message patterns and message components in detail in Chapter 5. • Message • Message channel • Pipes and filters • Message router • Message translator • Message endpoint Following are different integration architectures: for example, information portals, common business functions, and distributed business processes architectures, which help you to solve common problems of integrations such as aggregator pattern architectures, B2B (business to business) architectures, and service bus architectures (SOA). • Aggregator pattern architectures: There are many business processes where you should to access more than one system to answer a question to perform a single business function in an organization. Hence, information portals aggregate the information from multiple sources to display a holistic view. For example, you need to get data from business process 1, business process 2, and business process 3, aggregate the data from all processes, and display it on the dashboard, as shown in Figure 3-13. 80
