Abstract

This document describes how to create and test an example traffic violation decision service using a Decision Model and Notation (DMN) model in Red Hat Decision Manager 7.4. The procedures in this document are based on the Traffic_Violation sample project included in Business Central.

Preface

As a business rules developer, you can use Business Central in Red Hat Decision Manager to design a variety of decision services. Red Hat Decision Manager provides example projects with example business assets directly in Business Central as a reference. This document describes how to create and test an example traffic violation project based on the Traffic_Violation sample project included in Business Central. This sample project uses a Decision Model and Notation (DMN) model to define driver penalty and suspension rules in a traffic violation decision service. You can follow the steps in this document to create the project and the assets it contains, or open and review the existing Traffic_Violation sample project.

For more information about the DMN components and implementation in Red Hat Decision Manager, see Designing a decision service using DMN models.

Prerequisites

Chapter 1. Example projects and business assets in Business Central

Business Central contains example projects with example business assets that you can use as a reference for the rules or other assets that you create in your own Red Hat Decision Manager projects. Each sample project is designed differently to demonstrate decision management or business optimization assets and logic in Red Hat Decision Manager.

Note

Red Hat does not provide support for the example code included in the Red Hat Decision Manager distribution.

The following example projects are available in Business Central:

  • Traffic_Violation: (Decision management with DMN) Example traffic violation decision service using a Decision Model and Notation (DMN) model. Determines driver penalty and suspension based on traffic violations.
  • Mortgages: (Decision management with rules) Example loan approval process using rule-based decision assets. Determines loan eligibility based on applicant data and qualifications.
  • Employee_Rostering: (Business optimization) Example employee rostering optimization using decision and solver assets. Assigns employees to shifts based on skills.
  • OptaCloud: (Business optimization) Example resource allocation optimization using decision and solver assets. Assigns processes to computers with limited resources.
  • Course_Scheduling: (Business optimization) Example course scheduling and curriculum decision process. Assigns lectures to rooms and determines a student’s curriculum based on factors, such as course conflicts and class room capacity.
  • Dinner_Party: (Business optimization) Guest seating optimization using guided decision tables. Assigns guest seating based on each guest’s job type, political beliefs, and known relationships.

1.1. Accessing example projects and business assets in Business Central

You can use the example projects in Business Central to explore example business assets as a reference for the rules or other assets that you create in your own Red Hat Decision Manager projects.

Prerequisites

Procedure

  1. In Business Central, go to Menu → Design → Projects and click Try Samples.

    If a project already exists, click the three vertical dots in the upper-right corner of the Projects page and click Try Samples.

  2. Review the descriptions for each sample project to determine which project you want to explore. Each sample project is designed differently to demonstrate decision management or business optimization assets and logic in Red Hat Decision Manager.
  3. Select one or more sample projects and click Ok to add the projects to your space.
  4. In the Projects page of your space, select one of the new example projects to view the example assets for that project.
  5. Select each example asset to explore how the project is designed to achieve the specified goal or workflow.

  6. In the upper-right corner of the project Assets page, click Build to build the sample project or Deploy to build the project and then deploy it to Decision Server.

    Note

    You can also select the Build & Install option to build the project and publish the KJAR file to the configured Maven repository without deploying to a Decision Server. In a development environment, you can click Deploy to deploy the built KJAR file to a Decision Server without stopping any running instances (if applicable), or click Redeploy to deploy the built KJAR file and stop any running instances. The next time you deploy or redeploy the built KJAR, the previous deployment unit (KIE container) is automatically updated in the same target Decision Server. In a production environment, the Redeploy option is disabled and you can click Deploy only to deploy the built KJAR file to a new deployment unit (KIE container) on a Decision Server.

    To configure the Decision Server environment mode, set the org.kie.server.mode system property to org.kie.server.mode=development or org.kie.server.mode=production. To configure the deployment behavior for a corresponding project in Business Central, go to project Settings → General Settings → Version and toggle the Development Mode option. By default, Decision Server and all new projects in Business Central are in development mode. You cannot deploy a project with Development Mode turned on or with a manually added SNAPSHOT version suffix to a Decision Server that is in production mode.

    To review project deployment details (if applicable), go to Menu → Deploy → Execution Servers.

Chapter 2. Creating the traffic violations project

For this example, create a new project called traffic-violation. A project is a container for assets such as data objects, DMN assets, and test scenarios. This example project that you are creating is similar to the existing Traffic_Violation sample project in Business Central.

Procedure

  1. Log in to Business Central.

  2. Go to Menu → Design → Projects.

    Red Hat Decision Manager provides a default space called MySpace, as shown in the following image. You can use the default space to create and test example projects.

    Figure 2.1. Default space

    spaces teams
  3. Click Add Project.
  4. Enter traffic-violation in the Name field.

  5. Click Configure Advanced Options to expand the GAV fields and enter the following values:

    • Group ID: org.kie.example.traffic
    • Artifact ID: traffic-violation
    • Version: 1.0.0

  6. Click Add.

    The Assets view of the project opens.

Chapter 3. Decision Model and Notation (DMN)

Decision Model and Notation (DMN) is a standard established by the Object Management Group (OMG) for describing and modeling operational decisions. DMN defines an XML schema that enables DMN models to be shared between DMN-compliant platforms and across organizations so that business analysts and business rules developers can collaborate in designing and implementing DMN decision services. The DMN standard is similar to and can be used together with the Business Process Model and Notation (BPMN) standard for designing and modeling business processes.

For more information about the background and applications of DMN, see the OMG Decision Model and Notation specification.

3.1. Creating the traffic violations DMN decision requirements diagram (DRD)

A decision requirements diagram (DRD) is a visual representation of your DMN model. Use the DMN designer in Business Central to design the DRD for the traffic violations project and to define the decision logic of the DRD components.

Figure 3.1. DRD for the Traffic Violations example

Prerequisites

  • You have created the traffic violations project in Business Central.

Procedure

  1. On the traffic-violation project’s home page, click Add Asset.

  2. On the Add Asset page, click DMN. The Create new DMN window is opened.

    1. In the Create new DMN window, enter Traffic Violation in the DMN name field.
    2. From the Package list, select org.kie.example.traffic.traffic_violation.
    3. Click Ok. The DMN asset in the DMN designer is opened.
  3. In the DMN designer canvas, drag two DMN Input Data input nodes on to the canvas.
  4. Double-click each input node and rename one to Driver and the other to Violation.
  5. Drag a DMN Decision decision node on to the canvas.
  6. Double-click the decision node and rename it to Fine.
  7. Click the Violation input node, select the Create DMN Information Requirement icon and click on the Fine decision node to link the two nodes.
  8. Drag a DMN Decision decision node on to the canvas.
  9. Double-click the decision node and rename it to Should the driver be suspended?.
  10. Click the Driver input node, select the Create DMN Information Requirement icon and click on the Should the driver be suspended? decision node to link the two nodes.
  11. Click the Fine decision node, select the Create DMN Information Requirement icon, and select the Should the driver be suspended? decision node.
  12. Click Save and click Save again to confirm.

3.2. Creating the traffic violations DMN custom data types

DMN data types determine the structure of the data that you use within a table, column, or field in a DMN boxed expression for defining decision logic. You can use default DMN data types (such as string, number, or boolean) or you can create custom data types to specify additional fields and constraints that you want to implement for the boxed expression values. Use the DMN designer’s Data Types tab in Business Central to define the custom data types for the traffic violations project.

  15. Click ContextEntry-1, enter Total Points as the Name, and select number as the Data Type.
  16. Click the cell next to Total Points, select Literal Expression from the context menu, and enter Driver.Points + Fine.Points as the expression.
  17. In the cell below Driver.Points + Fine.Points, select Literal Expression from the context menu, and enter if Total Points >= 20 then "Yes" else "No".

  18. Click Save to open the Confirm Save dialog box and click Save again.

    You have defined how to calculate the fine and the context for deciding when to suspend the driver. You can navigate to the traffic-violation project page and click Build to build the example project and address any errors noted in the Alerts panel.

Chapter 4. Test scenarios

Test scenarios in Red Hat Decision Manager enable you to validate the functionality of business rules and business rule data (for rules-based test scenarios) or of DMN models (for DMN-based test scenarios) before deploying them into a production environment. With a test scenario, you use data from your project to set given conditions and expected results based on one or more defined business rules. When you run the scenario, the expected results and actual results of the rule instance are compared. If the expected results match the actual results, the test is successful. If the expected results do not match the actual results, then the test fails.

Red Hat Decision Manager currently supports both the new Test Scenarios designer and the former Test Scenarios (Legacy) designer. The default designer is the new test scenarios designer, which supports testing of both rules and DMN models and provides an enhanced overall user experience with test scenarios. If required, you can continue to use the legacy test scenarios designer, which supports rule-based test scenarios only.

You can run the defined test scenarios in a number of ways, for example, you can run available test scenarios at the project level or inside a specific test scenario asset. Test scenarios are independent and cannot affect or modify other test scenarios. You can run test scenarios at any time during project development in Business Central. You do not have to compile or deploy your decision service to run test scenarios.

You can import data objects from different packages to the same project package as the test scenario. Assets in the same package are imported by default. After you create the necessary data objects and the test scenario, you can use the Data Objects tab of the test scenarios designer to verify that all required data objects are listed or to import other existing data objects by adding a New item.

Important

Throughout the test scenarios documentation, all references to test scenarios and the test scenarios designer are for the new version, unless explicitly noted as the legacy version.

Chapter 5. DMN model execution

You can create or import DMN files in your Red Hat Decision Manager project using Business Central or package the DMN files as part of your project knowledge JAR (KJAR) file without Business Central. After you implement your DMN files in your Red Hat Decision Manager project, you can execute the DMN decision service by deploying the KIE container that contains it to Decision Server for remote access and interacting with the container using the Decision Server REST API.

For information about including external DMN assets with your project packaging and deployment method, see Packaging and deploying a Red Hat Decision Manager project.

5.1. Executing a DMN service using the Decision Server REST API

Directly interacting with the REST endpoints of Decision Server provides the most separation between the calling code and the decision logic definition. The calling code is completely free of direct dependencies, and you can implement it in an entirely different development platform such as node.js or .net. The examples in this section demonstrate Nix-style curl commands but provide relevant information to adapt to any REST client.

For more information about the Decision Server REST API, see Interacting with Red Hat Decision Manager using KIE APIs.

Prerequisites

  • Decision Server is installed and configured, including a known user name and credentials for a user with the kie-server role. For installation options, see Planning a Red Hat Decision Manager installation.

  • A KIE container is deployed in Decision Server in the form of a KJAR that includes the DMN model, ideally compiled as an executable model for more efficient execution: 

    mvn clean install -DgenerateDMNModel=yes

    For more information about project packaging and deployment and executable models, see Packaging and deploying a Red Hat Decision Manager project.

  • You have the container ID of the KIE container containing the DMN model. If more than one model is present, you must also know the model namespace and model name of the relevant model.
  • You have the DMN model deployed. For more information about project deployment, see Packaging and deploying a Red Hat Decision Manager project.

Procedure

  1. Determine the base URL for accessing the Decision Server REST API endpoints. This requires knowing the following values (with the default local deployment values as an example):

    • Host (localhost)
    • Port (8080)
    • Root context (kie-server)
    • Base REST path (services/rest/)

    Example base URL in local deployment for the traffic violations project:

    http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0

  2. Determine user authentication requirements.

    When users are defined directly in the Decision Server configuration, HTTP Basic authentication is used and requires the user name and password. Successful requests require that the user have the kie-server role.

    The following example demonstrates how to add credentials to a curl request: 

    curl -u username:password <request>

    If Decision Server is configured with Red Hat Single Sign-On, the request must include a bearer token: 

    curl -H "Authorization: bearer $TOKEN" <request>

  3. Specify the format of the request and response. The REST API endpoints work with both JSON and XML formats and are set using request headers:

    JSON

    curl -H "accept: application/json" -H "content-type: application/json"

    XML

    curl -H "accept: application/xml" -H "content-type: application/xml"

  4. (Optional) Query the container for a list of deployed decision models:

    [GET] server/containers/{containerId}/dmn

    Example curl request: 

    curl -u wbadmin:wbadmin -H "accept: application/xml" -X GET "http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0/dmn"

    Sample XML output: 

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<response type="SUCCESS" msg="Ok models successfully retrieved from container 'Traffic-Violation_1.0.0'">

  5. Execute the model:

    [POST] server/containers/{containerId}/dmn

    Note

    The attribute model-namespace is automatically generated and is different for every user. Ensure that the model-namespace and model-name attributes that you use match those of the deployed model.

    Example curl request: 

    curl -u wbadmin:wbadmin -H "accept: application/json" -H "content-type: application/json" -X POST "http://localhost:8080/kie-server/services/rest/server/containers/traffic-violation_1.0.0/dmn" -d "{ \"model-namespace\" : \"https://github.com/kiegroup/drools/kie-dmn/_60B01F4D-E407-43F7-848E-258723B5FAC8\", \"model-name\" : \"Traffic Violation\", \"dmn-context\" : {\"Driver\" : {\"Points\" : 15}, \"Violation\" : {\"Type\" : \"speed\", \"Actual Speed\" : 135, \"Speed Limit\" : 100}}}"

    Example JSON request: 

    {
  "model-namespace" : "https://github.com/kiegroup/drools/kie-dmn/_60B01F4D-E407-43F7-848E-258723B5FAC8",
