Materialized View Maintenance and Integrity Constraint Checking: Trading Space for Time
We investigate the problem of incremental maintenance of an SQL view in the face of database updates, and show that it is possible to reduce the total time cost of view maintenanc...

A Practical Algorithm to Find the Best Subsequence Patterns
Given two sets of strings, consider the problem to find a subsequence that is common to one set but never appears in the other set. The problem is known to be NP-complete. We gene...
