The term "integration" refers to the software-development activity in which you combine separate software components into a single system. On small projects, integration might consist of a morning spent hooking a handful of classes together. On large projects, it might consist of weeks or months of hooking sets of programs together. Regardless of the size of the task, common principles apply.

The topic of integration is intertwined with the topic of construction sequence. The order in which you build classes or components affects the order in which you can integrate them you can't integrate something that hasn't been built yet. Both integration and construction sequence are important topics. This chapter addresses both topics from the integration point of view.
