The Research Of XML Storage And Query Technology Based On Hypertable

With the development of Web technology, NOSQL Database has becoming hotspot in international database research. Moreover, with the development of the XML technology, it has gradually become a standard of representing and exchanging data on the Web. So researching the technology of XML management is valuable for Web-based applications.These papers classify and summarize XML storage approaches. There are four methods for storing XML data nowadays:file system, Native-XML Database, XML-Enabled Database. We introduce them in detail and compare the respective feature of them.In this paper, the most important work is present a plan based on Hypertable, which can record the path information of XML data, by analyzing the Hypertable's theory of storage and query. The storage procedures include two steps. Firstly, we parse XML data to TSV data, which fit for storage structure of Hypertable. Secondly, we load TSV data to Hypertable. The trait of this storage method is put the filename and path information store in one table. It can save time and enhance the query efficiency.We present a structured query way, which based on Hypertable. The procedures include two parts. First part is using Xpath-based query language, which was realized by query-transform function. Then using reconstructs function tranfer result to XML file. At last, testing the practicability of storage and qurery based on Hypertable.
