Lesson 2: Receive and Filter Notifications

In this lesson, you start creating an orchestration that receives notifications for changes to the Employee table. After the orchestration receives the notification, it extracts the type of notification and if the notification type is for an Insert operation on the Employee table, an “if” condition is used to perform subsequent tasks. In this lesson, you will perform the following tasks:

1. Add a one-way receive port and a Receive shape to the orchestration to receive the notification message.

2. Add an Expression shape that contains an xpath query to extract the type of notification.

3. After the notification type is known, add a filter to the orchestration by including a Decide shape. This shape decides whether the notification is for an Insert notification and then performs subsequent operations. If the notification is not for an Insert operation, the orchestration does not do anything.
