A Rules Engine Component by VDE Technologies LLC

In the RuleLab.Net system, Business Rules are composed and managed over the Internet or Intranet using the web-based Rules Designer. It allows users to associate an application XML data template with Rules, create a vocabulary of natural terms, graphically build complex logical expressions, test the Rules on data samples, and store the Rules in a database. Features include strong data types, reasoning, rule priorities and dependencies, calculation formulas, looping-data-structure support, and a built-in set of computational, aggregate and other data processing functions.

Rules and other system objects are stored in XML files that can be downloaded, modified, and uploaded to the online repository. Rule changes made online can be instantly deployed for runtime use by the applications integrated with the BRE. The forward chaining BRE parses XML application data against the ruleset, updates your data XML document, and returns it back to the application along with the comprehensive state information.

Written in .NET, the BRE component can be utilized as a managed assembly, a COM object, or through the Web Service. Comprehensive samples demonstrate how to invoke the BRE from a C# program or an AJAX script. Product extensions are available for building web site business logic and creating web-based expert systems.
