Rule Dialog (ORD) is a software product built on top of OpenRules® BDMS. It allows non-technical people to develop and maintain web-based questionnaires (dialogs) using only Excel and without a need to learn complex web programming techniques.

A questionnaire is a web application that can be described by a subject matter expert in terms of pages, sections, and different types of questions and answers.  Layouts of pages, sections, questions, and complex relationships between them can be expressed in a very natural way using simple and intuitive Excel tables. 

ORD is included in the standard complete OpenRules® installation.


The following documents describe the product:

Examples of web dialogs created with ORD:

Dialog Samples

ORD is highly customizable and expandable. Only basic concepts, (dialog, page, section, question, answer) are hard-coded in Java as a part of OpenRules Forms. The business and presentation logic for building complex questionnaires is presented in predefined Excel-based rule templates and layouts available for learning and changes. Thus, ORD is completely open-sourced.

ORD already includes a set of Questionnaire Templates that will be expanded by OpenRules and its customers.
