Because performance is a crucial issue in database systems, data caching techniques have been studied in database research field, especially in client-server databases and distrib...
In many application domains (e.g., WWW mining, molecular biology), large string datasets are available and yet under-exploited. The inductive database framework assumes that both s...
We give semantic characterizations of the expressive power of navigational XPath (also called Core XPath) in terms of first order logic. XPath can be used to specify sets of nodes...
