Structure-Aware Intelligent Data Routing in SciHadoop

QMDS: a file system metadata management service supporting a graph data model-based query language

File system metadata management has become a bottleneck for many data-intensive applications that rely on high-performance file systems. Part of the bottleneck is due to the limitations of an almost 50-year-old interface standard with metadata …

SciHadoop: Array-based Query Processing in Hadoop

Hadoop has become the de facto platform for large-scale data analysis in commercial applications, and increasingly so in scientific applications. However, Hadoop's byte stream data model causes inefficiencies when used to process scientific data that …

InfoGarden: A Casual-Game Approach to Digital Archive Management

Fusing Data Management Services with File Systems

File systems are the backbone of large-scale data processing for scientific applications. Motivated by the need to provide an extensible and flexible framework beyond the abstractions provided by API libraries for files to manage and analyze …

Integrating object and agent worlds

Repositories provide the information system's support to layer software environments. Initially, repository technology has been dominated by object representation issues. Teams are not part of the ball game. In this paper, we propose the concept of …

Sharing Processes: Team Coordination in Design Repositories

Information systems support for design environments emphasizes object management and tends to neglect the growing demand for team support. Process management is often tackled by rigid technological protocols which are likely to get in the way of …
