Daman BRMS Data Sheet

Daman BRMS 2.0 Overview
The Daman Business Rules Management System (BRMS) is the industry's most architecturally advanced product for the enterprise-wide representation and management of business rules.

Based on Daman's MDMS™ technology, the Daman BRMS harnesses the power of business rules by :

• Providing a consistent, declarative mechanism to represent business rules,
• Allows incorporation of legacy business rules,
• Capturing the metadata of business rules to facilitate administration, navigation and use of business rules,
• A powerful engine that includes patented performance features that ensure high-performance of applications that use these business rules

All this ensures that business rules can be changed, managed and shared much more efficiently across applications. The applications themselves can be developed, updated, and extended much more efficiently.

Key Features in BRMS 2.0
