Activiti in Action（实战Activiti）-第一章 BPMN 2.0: what’s in it for developers?（1）

This chapter covers

本章介绍

• Introducing the world of BPM
• 引入BPM世界
• Designing processes with BPMN 2.0
• 用BPMN 2.0设计流程
• Implementing a BPMN 2.0 process with Activiti
• 用Activiti实现BPMN 2.0流程

We are about to start our journey in designing business processes with BPMN 2.0 and implementing these processes with the open source BPM platform Activiti. But before we explore these topics, we need some background into business process management (BPM).

我们即将开始采用BPMN 2.0设计业务流程，并用开源BPM平台Activiti实现这些流程的旅程。但是，在我们开发这些主题之前，我们需要了解一些业务流程管理（BPM，Business Progress Management）的背景知识.

The definition of business process management (BPM) is really broad, and BPM vendors are broadening the term even further every day. Because we can’t (and don’t want) to cover the full spectrum of what is covered by BPM, this chapter defines the boundaries what we’ll cover in this book. You’ll experience that this book is not about the theory behind for example business processes, business rules, business activity monitoring and straight through processing. This book will show how to develop and deploy business processes with BPMN 2.0 and the Activiti process engine. So this chapter shows we’ll talk No Fluff just Stuff.

业务流程管理（BPM）的定义实际上相当宽泛，况且BPM供应商甚至每天都在扩展这个术语。因为我们不能（也不想）包含BPM所涵盖的全部范围，所以本章定义了我们在本书所涵盖的边界。你将亲身体验，本书不是关于示例业务流程，业务规则，业务活动监视和直接处理背后的理论。本书将展示如何采用BPMN 2.0和Activiti流程引擎开发和部署业务流程。所以本章展示了我们将谈论的话题：只是没有绒毛的东西。

But before we dive into code examples starting in section 1.5, we’ll first take a look at the topic of BPM. Once we have a good idea of this broad world, you’ll be introduced in the BPMN 2.0 specification and why it’s such an important industry standard. Then the theoretical foundation for this book is presented and we’ll look into BPMN 2.0 from a pure developers perspective. That’ll provide a good introduction before we finally start developing a simple process and run it with the Activiti process engine.

但是在我们尝试钻研在1.5节开始的代码示例之前，我们将先来看看BPM主题。一旦我们有了这个广阔世界的好主意，那么将介绍BPMN 2.0规范，以及为什么它是一个如此重要的工业标准。然后提出本书的理论基础。我们将一个纯开发者的角度审视BPMN 2.0。在我们最终启动开发一个简单流程并用Activiti流程引擎来运行它之前，那将提供一个良好的开端。

But we can’t start developing BPMN 2.0 processes before we get a clear understanding of BPM and the wide range of business theories, but also different technologies it covers. 

但是，在我们清楚理解BPM和广泛的业务理论以及所涉及的不同技术之前，我们不可以开始开发BPMN 2.0流程的过程。
