Mapping of MongoDB database document structure to XML schematic and propose a grammar in order to execute some fuzzy queries in XML

With the rapid growth of Internet and entering the technology into various aspects of human life, and subsequently, increasing the data volume to storage and transfer, relational databases cannot support management of large volume of data. Therefore, the NoSQL databases were emerged. On the one hand, due to the different formats of data in computer systems and databases, exchanging data between these systems are problematic on the internet platform. Therefore, exchanging information in a certain format such as XML can be very effective to solve this problem. On the other hands, due to the non-deterministic nature of data that users involved them, management of such information using the classic database systems leads to damaging the semantics. Therefore, in order to eliminate this challenge, the combination of database with the Fuzzy logic is proposed as a solution. Hence, adding the Fuzzy logic to XML standard can capable the XML to involve inaccurate data (Goran et al, 2012). Therefore, in this paper, after converting the MongoDB database documents to the XML documents, it has been tried to use the Fuzzy logic in XML documents. The proposed method has a higher capability compared to the previous works in terms of mapping the MongoDB commands to XML commands.
