OrientStore: A Schema Based Native XML Storage System

Abstract

This chapter discusses a schema based native XML storage system. The increasing number of XML repositories has provided the impetus to design and develop systems that can store and query XML data efficiently. Research to improve system performance has been largely concentrated on indexing paths and optimizing XML queries. The storage configuration of XML data on disk also has an impact on the efficiency of an XML data management system. Existing XML storage strategies can be classified into two categories: native XML storage and non-native XML storage. The main distinction between them is their data model. The former is based on the XML Data Models such as document object model (DOM), and object exchange model (OEM), while the latter is based on the traditional relational data model, or object-oriented data model. An evaluation of the alternative non-native storage strategies is presented.
