Deployment Options
Use decision model “VacationDays” to explore different ways to deploy it.
Learn by examples
Start with a decision model that already works.
OpenRules lets business users and subject-matter experts create, test, and maintain operational decision models without programming. Each sample combines a business glossary with decision tables that make the model’s logic visible.
Choose your starting point
Explore the installed sample library.
The openrules.samples workspace organizes complete projects by purpose, so you can begin with the capability closest to your decision.
Run a sample
See the complete model in action.
Open INTRO/VacationDays in openrules.samples and run test.bat to build and execute the decision model. Run explore.bat to open the Graphical Decision Modeling IDE, examine the automatically generated diagram, and debug the rules.
You can modify an existing project or create your own model, then deploy the decision service in the cloud or on premises and invoke it using JSON, XML, or Java.
