OpenRules Evaluation Sandbox

Analyze and Execute Standard and Custom Decision Models with No Downloads

 
Analyzing and Executing Standard and Custom Decision Models
  You may find many decision models included into the standard OpenRules installation at the OpenRules Evaluation Sandbox located at

                           http://openjvm.jvmhost.net/OpenRulesSandbox

You may also try Why-Analyzer to analyze the behavior of the predefined DMN-based decision models - just click on

                           http://openjvm.jvmhost.net/WhyAnalyzer

The graphical interface for OpenRules Sandbox looks like on the following screen:



Select any of the above models and click on the engine-button on the right. It will execute the selected model and will show you the execution results that may look like at the screen below:



After evaluating the standard OpenRules
® decision models, you may install the complete version to better understand the power of OpenRules®.

Creating and Executing Custom Decision Models

You may create and execute your own decision models using the standard decision models as prototypes. To do that, you need to:

1) Save the standard Excel-based model (e.g. DecisionHello.xls) and create a local version of your own model using Excel only (no custom Java files allowed)
2) Upload your Excel files to any publicly available web directory such as OpenRules sandbox: http://openrules.com/sandbox
3) Execute your decision model from the OpenRules Sandbox and analyze the produced results.

For the evaluation purposes you do not have to create any custom Java classes. You simply define your Decision called "Main" in Excel including: a decision, decision tables, glossary, and test data. Your model should be organized similarly to the model in the standard example "DecisionHello.xls". Let's assume that you've created a custom decision model in your local file "DecisionMy.xls". Then you need to upload this file to any web server. You may use OpenRules® public repository "http://openrules.com/sandbox/" . To do this, use any FTP client such as FileZilla. When you install and open FileZilla, you may access our repository by  creating a new connection with the following attributes:

  • Host: ftp://openrules.com

  • Username: or_sandbox

  • Password: <get the password by sending a request to support@openrules.com>

It will open the remote folder "http://openrules.com/sandbox", into which your decision models such as "DecisionMy.xls" may be uploaded.

To run your decision model, open your Internet browser with the URL 

http://openjvm.jvmhost.net/OpenRulesSandbox

It will display a webpage that looks like the one above. Enter the correct URL for the Custom Decision Model in the last row. e.g.:

          

Then click on the engine-button to execute your decision model. It will show the execution results similar to the above. If there are errors in your model, the proper error messages will be produced. You may fix the errors locally, upload the corrected Excel files, and try again until you receive the expected results.

Notes.

1) You may upload your decision model to your own remote server and just enter the proper link as the Custom Decision Model URL

2) The folder "http://openrules.com/sandbox/" may contains several other sample projects.  You may execute them too by entering the proper URLs and decision names. But please do not modify any of these projects. While you always may upload your decision models again, you probably would not like if other people mess with your remote projects.

___________________________________________________

Hopefully, you will find there capabilities to be sufficient for your evaluation. However, if you want to try other OpenRules® capabilities (like integrating your decision model with your own Java objects, debugging, producing execution reports in HTML, and more), you may download the evaluation version or go to the complete production download with all additional components.

Feel free to contact OpenRules® technical support at support@openrules.com with any questions or issues you may have. See also the Discussion Forum.
