This chapter introduced the concept of integration patterns. It also provided an integration pattern taxonomy, applied for both EAI as well as B2Bi. I covered the details behind seven primary integration patterns commonly applied today.
Chapter 4, "Integration Brokers," will introduce the first of the strategic e-Business Integration technologies: the integration broker. Integration brokers address the data integration layer and are used primarily, although not exclusively, within the enterprise. The chapter will discuss the fundamental attributes of the integration broker and explore how these attributes are critical to data integration. Chapter 4 will also provide a basis of evaluating integration brokers and assess some of the leading integration brokers on the market today.
