Here is an essential reference for anyone interested in the effective
management of semsistructured data. Since many new and advanced web
applications consume a huge amount of such data, there is a growing need
to properly design efficient databases. This volume responds to that
need by describing a semantically rich data model for semistructured
data, called Object-Relationship-Attribute model for Semistructured data
(ORA-SS). Focusing on this new model, the book discuss problems and
present solutions for a number of topics, including schema extraction,
the design of non-redundant storage organizations for semistructured
data, and physical semsitructured database design, among others.
