The confidence index and confidence index set (ciset) can be used to extend any classical theory. In particular, ciset can be applied to extend relational database theory to store and process conflicting pieces of information. In this paper, the importance of symmetry of an operator is demonstrated. The existing operators of ciset and ciset relational database are shown to be not symmetric. Possible alternate operators that are symmetric to replace the existing operators are introduced.
