This document discusses integration projects using the Apache Camel framework and Fuse Tooling. It provides an overview of Apache Camel, which is an open-source integration framework that uses established integration patterns. It then demonstrates how to implement a content-based router pattern using Apache Camel's XML and Java domain-specific languages. Finally, it describes how Fuse Tooling can be used in IDEs to graphically define routes, validate configurations, debug and test integrations both on-premise and in the cloud.
