Path-oriented integration method for complex trees

Abstract

The hierarchical data format becomes increasingly common. One of the problems arising with it is efficient tree integration, i.e. integration of XML databases. One possible approach is path-based integration, used among others in applications using XQuery and XPath database queries. This article offers a generalization for integration tasks based on this approach, as well as a short analysis of the result in terms of other existing integration criteria. The paper presents estimations for such criteria as Completeness, Minimality and Precision. © 2012 Springer-Verlag.
