A Novel Wide Area O.D.S Dependent Replicas Consistency Scheme in Transnational Hierarchy Topologies Enterprise Organizations

چکیده
The wide area data consistency become increasingly important in the GTEO as a result of using caching (Amiri,2003), middleware (Emmanuel,2004)(Jimenez,2003), edge server and database replication (Bettina,2000)(Decker,2003)(Zhang,2003) technologies. It is difficult for enterprise usage copies with local / remote ODS object partial dependency relationships to maintain their consistency. Today’s data integration solution based on document and application centralize conceptual will take more effort in application system. In addition, more and more database middleware API can’t truly reduce coding effort and maintenance costs. A novel application platform was proposed which consists of active, real time, automation, and global routing properties. The result can expand enterprise database system with ODS dependency replica correction maintenance abilities and provide adjustable update routing policies based on ODS dependency replicas usage mining results.

Middleware Support for Locality-aware Wide area Replication
Coherent wide-area data caching can improve the scalability and responsiveness of distributed services such as wide-area le access, database and directory services, and content distribution. However, distributed services differ widely in the frequency of read/write sharing, the amount of contention between clients for the same data, and their ability to make tradeoffs between consistency and av...
متن کاملKhazana: A Flexible Wide Area Data Store
Khazana is a peer-to-peer data service that supports efficient sharing and aggressive caching of mutable data across the wide area while giving clients significant control over replica divergence. Previous work on wide-area replicated services focussed on at most two of the following three properties: aggressive replication, customizable consistency, and generality. In contrast, Khazana provide...
متن کاملPerformance Evaluation of HARP: a Hierarchical Asynchronous Replication Protocol for Large Scale Systems
This report evaluates the performance of HARP, a hierarchical replication protocol based on nodes organised into a logical hierarchy. The scheme is based on communication with nearby replicas and scales well for thousands of replicas. It proposes a new service interface that provides different levels of asynchrony, allowing strong consistency and weak consistency to be integrated into the same ...
متن کاملA Scalable Replica Management Method in Peer-to-Peer Distributed Storage Systems
Large numbers of replicas in peer-to-peer distributed storage systems deteriorate inconsistency and load imbalance. According to those data management problems, a scalable replicas management method based on decentralized and unstructured peer-to-peer network is proposed. Replicas are partitioned into different hierarchies and clusters according to single replica replication, and then replicas ...
متن کاملImproving Cache Global Consistency and Hit Ratio in Dependency Objects with Semantic Spatial Locality Correlations
On requesting cache data in disk, the distribution of spatial locality is critical to access performance. Unfortunately, spatial locality properties of cached data is largely ignored, and only temporal locality is considered. Besides, an individual disk object might induce different dependency relations in different applications and possibly partial dependency to several distributed original da...
