Welcome!

Dufresne Consulting provides consulting services in the area of Information Technology specializing in Business Process Automation and integration of Legacy Systems with Web-based Business Applications.

Our Application and System Architects have extensive experience in the development of Business Applications and Back-end Systems using a Service Oriented Architecture (SOA) with technologies such as Java 2 Enterprise Edition (J2EE), C++, Python, and AJAX using a distributed development environment.

Top Engine 

We created Top Engine the Semantic Web Engine for the Enterprise. Top Engine is a world-class Business Rule Engine that utilize the Web Ontology Language (OWL) as the modeling language for the application Domain Model. This innovative approach provides an open architecture, free from vendor lock-in, that can model large and complex Business Process and their associated rules and policies.

Top Engine features an inference engine with forward and backward chaining with SPARQL-like query language. Top Engine is implemented in C++ using an optimized rete-network with truth maintenance.

At it's core, Top Engine, is a Resource Description Framework (RDF) Graph.

Top Engine is available as Open-Source and is released under a "dual licensing" business model. You may choose to use Top Engine under the free software/open source GNU General Public License (commonly known as GPL (v2)) or under a commercial license. Please contact us for more information.

Interview Engine 

From experience of implementing many integrations between Web-based front end with Legacy Back-end, we found a need to provide our Clients with tools that allow Business Analysts to define rules and policies without programing. This Interview Engine extents Top Engine using a Knowledge Management approach to rules definition.

The Interview Engine comes with Web-based configuration tools for defining rules and web-forms for deploying complex interview-style interactions with end-users without programing.
