Data-Structure-Model for Data Integration in Distributed Systems

Abstract

Data integration is one of key issues about data exchange and information sharing in distributed computing environment. It is necessary to develop a data structure model which can be used to enhance the data integration for distributed systems. In this paper, we propose a data structure model by which the organization of levels and flexibility of the expression within the systems can be established. This model is based on the spatial integration data method (SIDM) that builds a characteristic relationship between data types and data items. The conception and algebraic descriptions of the method is presented in terms of the object of spatial data and function of display of meta-data. A criterion is proposed to feature the algebraic operations for data integration being implemented in a distributed system.
