Data sharing in a large heterogeneous environment
R. Alonso, Daniel Barbará, Sarah Cohn · 2002
The issues involved in sharing information among a large collection of independent databases is explored. Some of the distinguishing features that characterize such large-scale environments (such as size, autonomy, and heterogeneity) are discussed. A multistep information sharing process for those systems is outlined and an architecture supporting that exchange is presented. A detailed description of a working prototype based on this architecture and some measurements of its performance are provided.>
