  1. Presents:Rally To Java Conversion Suite

  2. Rally was an excellent tool for its environment and its time: Character cell terminal Character cell terminal Character cell terminal Open VMS / RDB

  3. Rally is a well structured, easy to learn and efficient tool.

  4. But in the modern world Rally environment becomes a legacy one: • no Graphical User Interface • no support for n-tier architecture • sophisticated algorithms and database processing cases need to be maintained externally in other environments • Rally will be unsupported by Oracle in the next year • New VMS versions don’t support Rally

  5. Customer alternatives: • Rewriting of the application from the scratch. Very costly Time consuming May lead to the loss of business logic and user interface investments • Face-lifting – new GUI with old Rally system as a back engine. Still needs maintenance and development in unsupported Rally environment New VMS doesn’t support Rally • Conversion as a replacement methodology

  6. Conversion as a replacement methodology. • Saves all the investments in business logic. Opens the way to maintenance and further development in a new modern environment. Costs about ¼ from the rewriting. Takes just 2-4 man-months for an average application.

  7. Strategic decision: Java as a target conversion environment • Modern and powerful language. • Allows very flexible platform choosing • Allows staying with current platform on server side for a customer interested in it (VMS and RDB).

  8. Rally Conversion Java

  9. R2J Conversion steps: • Automatic generation of the full Rally application report. • Automatic generation of intermediate xml-representation. • Half-automatic revision of the xml-representation for unreported by Rally parts. • Automatic translation of the report into a set of Java and XML modules. • Manual treatment for reported in previous steps not matching or unsupported features. • Fine tuning for effective database support.

  10. Rally produces an application report including all the information about the application in unstructured form. Developed by MainTrend sophisticated parsing process automatically translates this reportinto an intermediate xml-representation.

  11. After producing the intermediate xml-representation for the Rally application, all the unreported points ( such as aggregate types for aggregate fields or texts for menu items) should be completed manually.

  12. Automatic generation transforms the Rally application into four Java packages: - data access layer package- business logic layer package- presentation layer package- façade (control layer) package

  13. Maintenance and enhancement of the resulting application can be easilydone in the new environment. JDataPanel is the base for both the convertedapplication and further development. JDataPanelgraphical designer isavailable as a standalone tool and as Oracle JDeveloper Add-in.

  14. JDataPanel designer as Oracle JDeveloper Add-in.

  15. The final step is the manual completion of the generated code and database access fine tuning. The automatic conversion part covers more then 80% of overall conversion efforts depending on the source application.

  16. R2J Conversion Suite • The same productivity and more, in a new modern application. • Customer can decide on the platform. A VMS / RDB based organization can proceed without a major change in it’s structure. The organization can but doesn’t have to migrate to another platform. • R2J provides the organization with a much lower cost and fast solution to their legacy applications. • The applications can be further developed by our GUI designing tools and framework alongside and integrated with the most cutting-edge commercial development tools.

  17. Thank you!
