A structure to support queries in object-oriented database using fuzzy XML tags

Abstract: Every day, we deal with the information, which are under uncertainty and managing this type of information with classical database systems brings a disadvantageous loss of data semantics along. Therefore, advanced database modeling techniques are necessary. Entrance of object orienting concept in databases helps relational database gradually use object oriented database in various fields. With the advances in this field, simple objects alone are not able to include complex data types and complex objects are necessary. On the other hand, for solving the problem of fuzzy data, several methods have been presented. One of these methods for modeling databases is an approach, which couples object-oriented database modeling with fuzzy logic. In this research, we observe the compilation of XML and fuzzy to represent a suitable approach for queries in object-oriented databases. In this paper, by combining sql and fuzzy XML tags, a language and independent database for storing and retrieving queries is prepared. We study database queries in two forms of simple and complex. In the form of complex, we use conjunctive queries.
