Developing a native storage structure for XML repository system in main memory

Abstract

Currently there are many commercial XML data management systems available. Most of these products are based on the traditional database management systems such as relational/object-oriented systems. Recently, some native XML data management systems are introduced. However, the previous XML repository structures are based on disk, it is inefficient to support real-time and mobile applications effectively. Hence, in this paper, we design a main memory-based XML repository structure to support real-time applications efficiently. To store and manage XML documents in native format, we design a logical data model for XML document. And we design a repository structure at physical level based on this logical model and finally implement the proposed repository structure.
