Research of information resources integration model based on grid service

On the basis of grid services technology, this passage proposes a distributed heterogeneous information resource integration model. The information resources are regarded as grid services which are registered to the service registry and provided services to the outside in the model. Thus the model can achieve the purpose of integration of information resources in the form of grid services. At the same time, the model Introducts Qos grid services evaluation which selects a more appropriate grid service according to each Qos properties and Qos attributes of each user preference. The model can be used to access the heterogeneous information resources.
