Measuring the degree of inconsistency of a knowledge base provides important context information for making easier inconsistency handling. In this paper, we propose a new fine-grained measure to quantify the degree of inconsistency of propositional formulae. Our inconsistency measure uses in an original way the minimal proofs to characterize the responsibility of each formula in the global inco...

The explosion of big data exacerbated the significance of data quality in decision support systems and data warehouses. Data inconsistency, as a significant data quality problem especially for heterogeneous databases, is mainly researched in three aspects: data integrity, semantics, and representational inconsistencies. The data integrity aspect has been well researched and implemented into DBM...

In a mobile computing environment, clients can access shared data irrespective of their physical location and can be updated by each client independently. This leads to inconsistency of the data. Several concurrency control techniques are proposed in literature to prevent data inconsistency. In this paper we first analyze the existing scheme of concurrency control without locking and justify it...

In a mobile computing environment, clients can access data irrespective of their physical location. Data is shared among multiple clients and can be updated by each client independently. This leads to inconsistency of the data. Due to limitations of mobile computing environment traditional techniques cannot be used. Several concurrency control techniques are proposed in literature to prevent da...
