DATVAL : A Model-Integrated Data Validation System

  DatVal is a model-based data validation system used in turbine engine testing developed for, and in use at, Arnold Engineering Development Center. It is designed to enhance the test engineer's ability to find corrupted test data streams. In its current configuration, about 10,000 data points arrive at DatVal approximately every two minutes. Data validation is performed by checking relationships among data streams based on a model of engine's underlying physics.

One of the more interesting aspects of DatVal is the integration of legacy code in the current system. Existing data validation routines were integrated as originally coded. This approach greatly reduced the amount of new software that had to be designed and written.
