Virtual enterprise (VE) relies on resource sharing and collaboration across geographically dispersed and dynamically allied businesses in order to better respond to market opportunities. It is generally considered that effective data integration and management is crucial to realise the value of VE. This paper describes a cloud-based data integration framework that can be used for supporting VE to discover, explore and respond more emerging business opportunities that require instant and easy resource access and flexible on-demand development in a customer-centric approach. Motivated by a case study discussing power incident management in the Spanish Electricity System, an effective on-demand application is also implemented to demonstrate how to use this framework to solve real world problems.
