Build and Run Decision Models. The workspace “OpenRulesDecisionManager” contains several examples of OpenRules projects (decision models) that can be used as prototypes for your own projects:

    • VacationsDays – this is an example of a basic OpenRules project
    • VacationsDaysLambda – this project demonstrates how to deploy the project VacationDays as AWS Lambda function
    • VacationsDaysSpingBoot – this project demonstrates how to deploy the project VacationDays as RESTfull Web Service and how to create a Docker image.

You can build and test a decision model by a simple double-click on the file “test.bat“.  For Mac or Linux, use the script-file “test“. When you try it for the first time, you may need to confirm that it’s safe to execute this script. If you make any changes in your Excel tables or configuration files, it will automatically re-build the model before running its tests. If it finds any errors, it will display them using the business terms pointing to the corresponding places in your Excel files. After the successful build, “test.bat” will test your model against test-cases described in the file “Test.xls”.  When you execute the decision model, the Decision Manager produces a user-friendly execution protocol and explanation reports in the HTML format in the generated folder “report“.

Every time you execute your decision model this execution will be reported to the AWS Marketplace metering service. After the first 30,000 free executions, AWS Marketplace will provide you with accurate monthly bills based on your actual number of executions and the above Pricing. All charges will go through AWS and you have an option to cancel your subscription at anytime.
