摘要：Even though data integration has been there for long, integrating e-health data remains an open research challenge. Many studies have discussed data integration approaches in isolation, causing a disjoint of information flows and narrowing the understanding of alternative solutions in the cause of choosing an appropriate approach for integrating e-Health data. This problem can be solved by undertaking a comprehensive review on different approaches and techniques in data integration as well as paradigm in e-Health frameworks. The main contribution of this paper is a narrative description of most widely used integration architectures as well as comparative analysis of each of them. The review reveals that despite the business needs of integration approach, each has limiting factors based on the data size, unstructured or structured nature of data set as well as business agility of the organization. Moreover, it is found that some technologies were not designed for data integration but for document management or information integration. It is concluded that data integration approaches and the field in which it applies mostly, is widely spread that always results in integration problem. Also, it is noted that designing a framework for integrating e-Health data using web service approach in a distributed network characterized with short lived connection is still a challenge
