The NASA Center for Climate Simulation (NCCS) plays a lead role in meeting the computational and data management requirements of climate modeling and data assimilation. Scientific data services are becoming an important part of the NCCS mission. The NCCS Data Management System (DMS) is a key

This paper introduces Clustera, an integrated computation and data management system. In contrast to traditional cluster-management systems that target specific types of workloads, Clustera is designed for extensibility, enabling the system to be easily extended to handle a wide variety of job

ABSTRACT Peer data management systems (PDMS) offer a flexible architecture for decentralized data sharing. In a PDMS, every peer is associated with a schema that represents the peer's domain of interest, and semantic relationships between peers are provided locally between pairs (or small

Computer systems for data management are increasingly concerned with the authorization problem: the problem of creating and managing the matrix of users, objects, and allowable operations. This paper discusses the authorization problem and explains why the problem is likely to become more complex

We survey the current state-of-the-art in (commercial) Product Data Management (PDM) systems. After identifying the major functions of PDM systems, we indicate various shortcomings of the current PDM technology. An important shortcoming is in the representation and use of functions. We review

A structural health monitoring system based on MATLAB Web Server is proposed and its prototype system is presented. In addition, a simple networked sensor system to be used for the health monitoring system is also proposed. The system transfers the data automatically through the Internet

Development of systems based on one language makes the Internet domain-specific and hampers internation-alization. This paper presents a three-layer architecture that facilitates retrieving of any type of data composed or indexed in one language via a query formulated in another language
