Allocating data fragments in distributed database systems is an important issue in distributed database (DDB) systems. In this research work, we will show how rule based policy languages can be used to represent different data fragment allocation techniques. Results indicate that, using rule based languages like prolog can significantly simplify the representation of such algorithms for any fur...

The CAP Theorem is a frequently cited impossibility result in distributed systems, especially among NoSQL distributed databases. In this paper we survey some of the confusion about the meaning of CAP, including inconsistencies and ambiguities in its definitions, and we highlight some problems in its formalization. CAP is often interpreted as proof that eventually consistent databases have bette...

Cloud computing is the way by which we connect to servers, large systems into a distributed secure manner without worrying about local memory limits. Here, in this paper, proposed Novel database architectural model for mobile cloud (NDDAMMCC). Accelerating exponential growth of wireless technologies and Internet are following Nielsen’s Law Bandwidth, new era computing. In recent technological e...
