+# Pack Transaction Demo
+This demo simulates a booking application including three services:
+* pack-booking
+* pack-car
+* pack-hotel
+
+## Running Demo
+1. run the following command to create docker images in saga project root folder.
+```
+mvn package -DskipTests -Pdocker -Pdemo
+```
+
+2. start application up in saga/saga-demo/pack-demo with the following command
+```
+docker-compose up
+```
+
+## User Requests
+1. Booking 2 rooms and 2 cars, this booking will be OK.
+```
+curl -X POST http://{docker.host.ip}:8083/booking/test/2/2
+```
+Check the hotel booking status with
+```
+curl http://{docker.host.ip}:8081/bookings
+```
+Check the car booking status with
+```
+curl http://{docker.host.ip}:8082/bookings
+
+```
+
+2. Booking 3 rooms and 2 cars, this booking will case the hotel order failed and trigger the compansate operation with car booking.
+```
+curl -X POST http://{docker.host.ip}:8083/booking/test/3/2
+```
+Check the hotel booking status with
+```
+curl http://{docker.host.ip}:8081/bookings
+```
+Check the car booking status with
+```
+curl http://{docker.host.ip}:8082/bookings
+```
+The second car booking will be marked with **cancel:true**
+
+
+**Note** transactions and compensations implemented by services must be idempotent.
