XML is emerging as a new major standard for representing data on the world wide web. Several XML storage models have been proposed to store XML data in different database management systems. The unique feature of model-mappingbased approaches is that no DTD information is required for XML data storage. In this paper, we present a new modelmapping-based storage model, called XParent. Unlike the ...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

Querying large datasets distributed over thousands of endsystems is a challenge for existing distributed querying infrastructures. High data availability requires either replicating or centralizing the dataset but both require infeasibly high network bandwidth. In-situ querying provides low bandwidth overheads but requires users to tolerate low data availability. This paper advocates partial da...

In recent years, materialized views (MVs) are widely used to enhance the database performance by storing pre-calculated results of resource-intensive queries in the physical memory. In order to identify which queries may be potentially materialized, database transaction log for a long period of time should be analyzed. The goal of analysis is to distinguish resource-intensive and frequently use...

Data-intensive Web sites serve large volumes of pages whose content is dynamically extracted from a database. Such Web sites have very high software development and maintenance costs and in general o er poor response times due to the heavy interaction with the database system. This paper introduces the Weave management system developed at INRIA, which alleviates the above shortcomings of data-i...

A fundamental issue that any control-based synchronization should address is how to minimize both the overheads of the synchronization and the processor idling due to the variation in the arrival time of the synchronizing processors. This paper proposes two techniques to alleviate the above two problems in a large-scale shared-memory multiprocessor. First, the notion of delayed global-materiali...
