Revisiting "Fragmentation of XML Documents"

Abstract

The article "Fragmentation of XML Documents" in this issue is a reprint of our original contribution to the 2003 Brazilian Symposium on Databases [Ma and Schewe 2003]. It is one of our early publications devoted to the development of a sound theory of distribution design for complex-value databases, a notion we use as an umbrella for all kinds of databases with tree-structured objects such as nested relational, object oriented and also XML databases. Our goal was to extend and generalise the known approach by fragmentation and allocation - replication was not considered - for relational databases.
