XML is gradually accepted as a standard for representing, accessing, and exchanging data in internet applications. It poses many new challenges to XML storages or XML repositories. The data centric approach of XML has necessitated the definition of integrity constraints for XML. Integrity constraints have proved fundamentally important in Relational Database management. We introduce Fuzzy Logic based constraints using triangular membership function and Trapezium shape membership functions. In this paper, we have introduced a fuzzy constraint-based framework to model the schema matching problem. Our approach is able to handle uncertainty in schema matching and data inconsistency in Native XML Database systems by exploiting fuzzy constraints. Our approach will restrict invalid XML data into XML Database by using fuzzy domain integrity constraints.
