DObjects: Enabling Distributed Data Services for Metacomputing Platforms
Source: VLDB Endowment
Many contemporary applications rely heavily on large scale distributed and heterogeneous data sources. The key constraints for building a distributed data query infrastructure for such applications are: Scalability, consistency, heterogeneity, and network and resource dynamics. The authors designed and developed DObjects, a general-purpose query and data operations infrastructure that can be integrated with meta-computing middleware. This paper proposal describes the architecture and the dynamic query processing functionalities of the data services and shows how they are integrated with a metacomputing framework offering users an open platform for building distributed applications that require access to data integrated from multiple data sources.
