Continual rebinding of data sources

摘要

A method, system and computer program for rebinding a binding expression to an appropriate network resource in response to changes in the requirements placed upon the resources or in response to changes in the properties of the currently bound network resource. The binding expression includes a data specification describing the properties required for the resource. Rebinding entails obtaining a list of potential appropriate network resources, selecting an appropriate network resource from the list, and rebinding the binding expression to that resource.
