There are many common challenges to integrate and share information resources in enterprise or industrial environment, for example, heterogeneous structure of data sources, dynamical changing of source location and schema, sharing information across multiple autonomous administrative domains, fine-grained access control, and personalized requirements. Although it is possible to build a specialized solution to meet any scenario requirements, the solution, which is very suitable to the specialized scenario, may not be available to other scenarios. Based on Web Services technology, Vega Information Grid (VIG) abstracts commonality of requirements and addresses these issues by information virtualization. A suite of toolkit, which provides functionalities suitable for different scenarios, enables enterprise users to acquire and deploy information cost-effectively in a virtual grid platform, and to benefit greatly form the decrease of the full life cycle time and the cost of management and changes of sharing information. This paper introduces its information virtualization model based relation schema, and decoupled architecture supporting personalized utilization pattern.
