“Sent the correct data to the right place in the right time” is the basic requirement of battlefield data distribution system. The increase of widely distributed combat nodes leads to an increased information exchanges between them which can have very different requirements for data exchange; these nodes are developed with different architecture, programming language or operating systems, which leads...
In distributed network, replicas are usually used to elevate data reliability and access efficiency. With the explosion of data quantity and complexity of network environment, the problem of replica consistency maintenance in data-intensive is confronted with challenge. The paper selects replica consistency maintenance in decentralized data centers as subject investigation. Firstly, we introduce the...
Cloud computing is a new trend to provide computing capacity and data storage in a pay-as-you-go model across Internet. Data management is a challenging task in cloud computing. In this paper we surveyed the state of the art of data management in cloud computing, discussed the issue about balance between consistency and scalability cloud data management and presented a feasible solution. We also highlighted...
