City-wide smart healthcare appointment systems based on cloud data virtualization paaS

Abstract

While the cloud computing benefits healthcare IT modernization, it introduces new challenges for data integration, which is crucial for information sharing, data mining and business intelligence applications. Data virtualization brings a new strategy and related technologies to cope with these challenges, particularly suitable for cloud data services and SaaS (Software-as-a-Service) applications. The paper discussed a unique architecture and related technologies to implement the data virtualization for cloud data. The paper also demonstrated how this technology can be used in the real-world applications, and a city-wide healthcare appointment system has been implemented for example.
