Basing on GA to Store XML Data in RDBMS

With the development of XML, XML data management technology is receiving more and more attention, and XML storage is key in the XML data management system Here, a new method is presented, which is based on the cost model for XML data in a relational database in order to provide different data schema for different users and requirements Then, this XML storage problem is turned into an optimal problem, and a genetic algorithm is introduced to solve this problem Experiments are done to test this method and it is shown that this method is feasible and efficient, and it can be used to design different schema according to different user query requirements
