Dynamical Detecting Technique of Nonfunctional Dependence Program Invariant

In this paper, the notation of program invariant was described, and a theory model of dynamical generating technique of invariants was researched. Then, the technology of dynamical generating technique of invariants of nonfunctional dependence was discussed. A new method of dynamical generating technique of invariants of nonfunctional dependence based on the theory of database was showed. Then, a series of detecting measures of specific nonfunctional dependence invariants were proposed .Many kinds of program invariants can be dynamically discovered by the means.
