CLAS-A formal aid to data elements identification

The method CLAS (Continuous Logic Attribute Synthesis) is a formalisation of the standard method named Synthesis of Attributes used for identification of entities and attributes in information systems design. It differs from the original method in a sense that the subjectiveness in the procedure of evaluation of parameters is eliminated by introducing formalised quantitative measures for elementary criteria. Also, the three global identification criteria which may cause a contradiction are reduced to one by the use of continuous logic functions.
