OrientX: An Integrated, Schema Based Native XML Database System

摘要

The increasing number of XML repositories has stimulated the design of systems that can store and query XML data efficiently. OrientX, a native XML database system, is designed to meet this requirement. In this paper, we described the system structure and design of OrientX, an integrated, schema-based native XML database. The main contributions of OrientX are: a)We have implemented an integrated native XML database system, which supports native storage of XML data, and based on it we can handle XPath& XQuery efficiently; b)In our OrientX system, schema information is fully explored to guide the storage, optimization and query processing.
