Abstract: “This paper provides an evaluation of some existing data integrations approaches according to the Patrick Ziegler’s ASME criteria for evaluating. These criteria for evaluating identify the characteristics of integrated approaches and investigate the existing of data integration approaches for their support for user-specific perspectives. Through this review, this paper aims to identify some potential implementation methods and architectures that support for a truly user-specific perspective in the context of the structured, semistructured, and unstructured data integration approaches”

Keywords: Information integration, Data integration, Data integration approaches, User-Specific Perspectives.
