Part 1. The basics

In this book we discuss events. Many people associate the word event with a meaningful happening in their lives such as a graduation party or wedding. If you wanted to plan a wedding event, you would need to understand the basics, such as terminology for discussing plans with service providers, the family constraints that affect the nature of the event, and the different types of ceremonies available.

We start this book by explaining the basics of event processing. If you are already familiar with the basics you can browse through part 1, taking note of the terminology that we use in this book. If you’re not sure that you know what event processing is all about, this part of the book should fill in the blanks for you.

Part 1 consists of chapters 1 and 2. Chapter 1 provides a bird’s-eye view of event processing. It explains what we mean by events and event-driven behavior. It includes some examples and relates them to different types of event processing. It also positions event processing within the enterprise computing universe and introduces the Fast Flower Delivery example application that will accompany us throughout the book. Chapter 2 discusses the architectural concepts and building blocks required to construct event processing systems.
