Strong data types, calculation formulas, looping-data-structure support, and many other features add power to the forward chaining Rules parser of the RuleLab.net BRE. The built-in set of computational, aggregate and other data processing functions can be customized. RuleLab.Net has been designed for easy integration with existing applications supporting XML. Written in .NET, the BRE component can be utilized as a managed assembly, a COM object, or through the Web Service. BRE component Clients can synchronize the Rule files with the online repository. Rule changes made online can be instantly deployed for runtime use by the applications integrated with the BRE. The convenient Web interface allows Business users to update the Rules over the Internet. RuleLab.Net lets you turn your application into a rule-based system.
