Build a hotel booking application using the Business Rules service in Bluemix
The Business Rules service hosted in Bluemix and powered by Operational Decision Manager allows you to define, deploy, and maintain business rules and policies separately from your application code. To demonstrate the benefits of decoupling the lifecycle of the calling application from the business logic (rules) running in a cloud service, we build a simple hotel booking application in a Node.js runtime bound to a Business Rules service that calculates the booking rates. This article will show you how to deploy and execute business rules in the cloud environment. You will then be able to extend this application with more complex rules or build your own application very easily.
