摘要：

This paper describes the design of a system that facilitates Extracting, Interconnecting and Accessing Heterogeneous Data Sources. Data sources can be static or active: static data sources include structured or semistructured data like databases, XML and HTML documents; active data sources include services which can be any executable programs such as C, C++ programs or Java classes. Users interact with the system using XQuery language. We have extended the XQuery language in order to call services. In this paper services resolve conflicts between static data sources (naming conflicts, data representation conflicts, data scaling conflicts...) in order to obtain an integrated view of data.
