WebSphere ILOG Business Rules for zOS

Overview

The WebSphere ILOG business rule management system (BRMS) product line provides a comprehensive set of capabilities that enable Business and IT functions within the organization to work together collaboratively for authoring, maintaining and deploying decision logic that is critical to business systems.

WebSphere ILOG Business Rules for z/OS brings powerful rule application development and execution functionality to mainframe systems, greatly improving policy change management and automated decisioning.

Business rules drive critical applications and enable operational decisions to be automated. Business Rules for z/OS facilitates the ability to move from manually coding rules to service-based rule execution as part of a progressive application modernization strategy.

Benefits of Business Rules for z/OS

• Externalize critical decision logic, so that it can be more easily maintained, governed and implemented as it evolves over time.
• Makes decision logic easily accessible and re-useable across the organization.
  
  • Rules can be defined in a customizable business vocabulary using a variety of rule metaphors, including decision tables, text-based rules and rule flows (combining multiple rulesets in a defined execution sequence).
  • Rules can be easily shared across business applications, ensuring consistency in the implementation of business policies across the organizations applications and systems.

• Reduces the amount of time, effort and cost required to develop and maintain applications by separating business decision logic from core application code. By managing rules outside of applications, the code base becomes more stable and less likely to be affected by change.
• Tools and environments are designed specifically for the unique needs of different technical stakeholders involved in rule managementApplication Developers, Systems Architects and IT Operations.
• Build and deploy rule-based applications on z/OS SOA-based decision services, or generate Enterprise COBOL code which can run directly inside COBOL applications by leveraging WebSphere ILOG Rules for COBOL module.
• Provides a flexible approach to application modernization efforts.
  
  • With Business Rules for z/OS, rules can be executed using the JRules Rule Execution Server running on WAS on z/OS or the rules can be generated as an Enterprise COBOL sub-program which can be called within COBOL applications.
  • What ever the option chosen for execution, the exact same rules repository can be leveraged to manage the decision logic.
  • Business Rules for z/OS can be used in conjunction with Rational Asset Analyzer to identify and manage business rules embedded in core mainframe programs and to achieve Business rule modernization

Advancing To Full Business Rules Management

WebSphere ILOG Business Rules for z/OS is the initial step in adopting a business rules approach on the mainframe. By bringing together the JRules development and execution environments, along with Rules for COBOL code generation capability, you gain all the benefits described above.

Business Rules for z/OS is enhanced with the addition of WebSphere ILOG Rule Team Server and Decision Validation Services, which bring capabilities for allowing non-technical business users and subject matter experts to participate in the maintenance and governance of business rules. By advancing to a full Business Rules Management solution, technical staff can focus on improving applications, while giving the line-of-business visibility and control over changes to decision logic that drive application behavior.
