Distributed query evaluation on semistructured data
Dan Suciu
Pages: 1-62
DOI: 10.1145/507234.507235
Semistructured data is modeled as a rooted, labeled graph. The simplest kinds of queries on such data are those which traverse paths described by regular path expressions. More complex queries combine several regular path expressions, with...

Atomicity and isolation for transactional processes
Heiko Schuldt, Gustavo Alonso, Catriel Beeri, Hans-Jörg Schek
Pages: 63-116
DOI: 10.1145/507234.507236
Processes are increasingly being used to make complex application logic explicit. Programming using processes has significant advantages but it poses a difficult problem from the system point of view in that the interactions between processes cannot...

A logical foundation for deductive object-oriented databases
Mengchi Liu, Gillian Dobbie, Tok Wang Ling
Pages: 117-151
DOI: 10.1145/507234.507237
Over the past decade, a large number of deductive object-oriented database languages have been proposed. The earliest of these languages had few object-oriented features, and more and more features have systematically been incorporated in successive...
