+<p>模拟一个简单的旅行应用，展示如何使用ServiceComb提供的Saga方案保证微服务间数据一致性。</p>
+
+<p>旅行应用包含四个微服务：</p>
+<ul>
+ <li>机票预订服务(flight-booking-service)</li>
+ <li>租车服务(car-rental-service)</li>
+ <li>酒店预订服务(hotel-reservation-service)</li>
+ <li>支付服务(payment-service)</li>
+</ul>
+
+<p>机票预订、租车、酒店预订服务间无依赖关系，使用自己的数据库，通过HTTP协议通信。
+在以上三个服务的预订成功，支付完成后才能满足一个成功的行程，否则不能成行，Saga自动补偿。</p>
