Chapter 5. 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.
The following example projects are available in Business Central:
- Mortgages: (Decision management) Example loan approval process using 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.
5.1. 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
- Business Central is installed and running. For installation options, see Planning a Red Hat Decision Manager installation.
Procedure
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.
- 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.
- Select one or more sample projects and click Ok to add the projects to your space.
- In the Projects page of your space, select one of the new example projects to view the example assets for that project.
- Select each example asset to explore how the project is designed to achieve the specified goal or workflow.
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.
NoteYou 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.modesystem property toorg.kie.server.mode=developmentororg.kie.server.mode=production. To configure the deployment behavior for a corresponding project in Business Central, go to project SettingsGeneral 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 SNAPSHOTversion suffix to a Decision Server that is in production mode.To review project deployment details (if applicable), go to Menu
Deploy Execution Servers.
