Information integration systems provide a uniform query interface to a set of sources. One of the key challenges for an information integration system is to provide maximally comp...
Virtual views are a mechanism that facilitates re-use and makes queries easier to express. However the use of iterative view definitions makes very simple query evaluation and an...
Abductive diagnosis is an important method to identify explanations for a given set of observations. Unfortunately, most of the algorithmic problems in this area are intractable. ...
A natural trend in most of the engineering disciplines is the construction of systems from components. This has the potential to reduce costs and increase reliability, provided th...
Abstract. A distributed system is fault-tolerant if it continues to perform correctly even when a subset of the processes becomes faulty. Faulttolerance is highly desirable but oft...
