Abstract: There are many common challenges to integrating and sharing information in distributed environment; for example, heterogeneous structure of data sources, dynamic changing of source location and schema, sharing information across multiple autonomous administrative domains, and personalised requirements. Although it is possible to build a specialised solution to meet any scenario requirements, the solution, which is very suitable to the specialised scenario, may not be available to other scenarios. The Vega Information Grid (VIG) abstracts the commonality of requirements and addresses these issues by information virtualisation. It is a toolkit, which provides functionalities suitable for different scenarios, enables users to acquire and deploy information cost-effectively in a virtual grid platform, and to benefit greatly from the decrease in the full life cycle time. This paper introduces its information virtualisation model, decoupled architecture, and virtual database engine to integrate decentralised data sources.

Keywords: information grid; information virtualisation; decoupled architecture; virtual database engine; information sharing; information integration; decentralised data.
