Legacy Navigator™

100% Java Graphical Process Modeling for Complex Integration

legnav_cdcover.gif Legacy Navigator is the industry's most advanced process modeling solution for legacy systems application integration and is designed, as part of Red Oak's Application Integration Framework, to dovetail seamlessly with the Legacy Integrator Runtime Server Module. Legacy Navigator simplifies the integration of complex, vitally strategic applications that are the bedrock of any Fortune 500 enterprise, and that typically include hundreds of screens, representing thousands of individual interaction transactions. This is a state-of-the-art XML process modeling technology that permits transactions to be visually defined, captured, programmatically integrated and easily maintained.

Legacy Navigator Features

  • 100% Java
  • 100% compliant with Legacy Integrator
  • 100% data-driven and configurable
  • Full programmatic integration with any EAI or B2Bi infrastructure
    • Seamless, fully automated approach
    • Reduces development time
    • Simplifies ongoing maintenance
  • Enables practical development and maintenance of complex integrations
  • Resource leverage
    • Legacy applications unchanged
    • Standard industry protocols
    • Allows integration modifications without code changes

The Legacy Navigator suite consists of these three primary components:

XML Screen Definition

Legacy Navigator's XML Screen Definition defines the target application's screens and components in XML data elements. Then, a Java API encapsulates all details associated with accessing specific screen components and consolidates them into an XML-based repository. When a screen layout changes, the Java code is unaffected and only the screen's definition has to be changed.

XML Process Model Engine

Integrating terminal-based systems often presents a significant challenge, with hundreds of screens and numerous navigational paths available for every transaction. To address these complex systems, Legacy Navigator implements a process engine that allows screen navigation to be data driven. The navigation for each transaction is captured during the build in an XML-based process model and then executed at runtime by the process engine. Changes in the navigation path (alternative paths, popup screens, exception paths, etc.) are easily incorporated into the process model.

This approach works where more traditional code-based designs often fail, and dramatically reduces the amount of code required.

Process Model Editor

The third primary component is the Process Model Editor, which defines the transitions between screens in the target application and facilitates the construction of new models. This visual definition also simplifies the maintenance of these complex navigation paths, because changes need only be made to the graphical process model.

The three components of Legacy Navigator are written entirely in Java and have been specifically designed for server-based implementation. The resulting technology takes full advantage of the benefits of server-based applications (centralized access and management, etc.) and greatly simplifies connectivity and maintenance of true integration with all IBM mainframe and I-Series legacy applications. When Legacy Navigator's SDK is coupled the Legacy Integrator Runtime Server Module they permit the incorporation of application transactions and data from any of these legacy applications to be seamlessly integrated with any of the major EAI messaging systems, from vendors such as IBM CrossWorlds, webMethods, Vitria, SeeBeyond and TIBCO.

According to the Gartner Group, 70% of all corporate data still resides on these legacy systems and if an existing internal application requires data from any other legacy application in the enterprise, Legacy Navigator and Legacy Integrator can easily enable this programmatic connectivity.

Red Oak's Transaction Integration™ Java products also provide customers with fast, efficient programmatic connectivity to Application Server solutions, from vendors such as BEA, IBM, Oracle and Sun, and any of the major enterprise systems, including Siebel, Peoplesoft, SAP, and JD Edwards. This functionality enables large corporations to capitalize on their massive investment in legacy applications and extend their reach to the Internet applications necessary for eBusiness.
