Now, managers, application developers and programmers have on-line, interactive access to information that's critical to ongoing changes and upgrades to mainframe systems.  VirtualSource is the first real alternative to tedious, time-consuming, expensive, and often error-prone, methods of manual documentation.

VirtualSource gives maintenance programmers instant access to important program components that are used throughout the full application. The access to Application-wide data element usage is immediately available even when editing or reviewing an individual program.  Equally important to its usefulness is that the files that contain this inquiry information can be updated as often as required, since it processes only the programs that have been changed daily, weekly, monthly, etc.  This continous update ability is based on SystemVision SVCommands parsing engine, which means that users inquiries are alway dealing with up-to date program information.

Since it is all "source-driven", VirtualSource can routinely update its database files without reprocessing the entire source library when only a few members are changed.  The process is not a static "one shot" event.  It's a dynamic ongoing process that continously monitors each application throughout its entire life cycle.

Another important aspect of VirtualSource's very extensive inquiry VBASE is the fact that the inquiry file is immediately accessible to the user, even when they are editing a program and changing the code.  In addition, if the inquiry suggests other programs should be immediately reviewed, there is a simple "point and click" process to browse (or edit) any othr program in the application.

VirtualSource's Business Rule Extraction process is highly automated.   It can locate all uses of relevant data elements, and identify each procedural use of those items.  It's a powerful process that will help ensure your success in an application re-engineering or migration effort.

VirtualSource's Cause and Effect feature will identify, for a specified data element, the (CAUSE) factors that contribute to its modification, or (EFFECT), the data elements it may modify, if a change is made.
