A Concentration of Measure Approach to Database De-anonymization [PDF]
arXiv, 2019 In this paper, matching of correlated high-dimensional databases is investigated. A stochastic database model is considered where the correlation among the database entries is governed by an arbitrary joint distribution. Concentration of measure theorems such as typicality and laws of large numbers are used to develop a database matching scheme and ...

Coded Data Rebalancing for Decentralized Distributed Databases [PDF]
arXiv, 2020 The performance of replication-based distributed databases is affected due to non-uniform storage across storage nodes (also called \textit{data skew}) and reduction in the replication factor during operation, particularly due to node additions or removals.

Distributed Database Systems in the Dynamic Networks Environment
Communications, 2011 This article describes a new architecture of a distributed database system, which is designed especially for the dynamic networks environment. Problems with the architecture of a traditional distributed database system are explained, and a solution is ...

Database Consistency Using Update-Ordering in Distributed Databases
Journal of Algorithms & Computational Technology, 2007 Database consistency is one of the major issues in replicated database in distributed database systems. The logical design for the replicated nodes and the transaction management mechanism are two aspects that give a serious impact to the performance and

Large-scale Biological Meta-database Management [PDF]
, 2015 Up-to-date meta-databases are vital for the analysis of biological data. However,the current exponential increase in biological data leads to exponentially increasing meta-database sizes. Large-scale meta-database management is therefore an important challenge for production platforms providing services for biological data analysis.

Query Optimization Techniques In Graph Databases [PDF]
International Journal of Database Management Systems ( IJDMS )
Vol.8, No.4, August 2016, 2016 Graph databases (GDB) have recently been arisen to overcome the limits of traditional databases for storing and managing data with graph-like structure. Today, they represent a requirement for many applications that manage graph-like data, like social networks.

Record matching method based on local CON model in distributed database
Tongxin xuebao, 2011 For existing record matching methods needed much artificial participation of experts or depend on heuristic rules heavily,and they could not handle the problem of large-scale data,A record matching method based on the local CON model was proposed.The ...

Fundamental Limits of Database Alignment [PDF]
arXiv, 2018 We consider the problem of aligning a pair of databases with correlated entries. We introduce a new measure of correlation in a joint distribution that we call cycle mutual information. This measure has operational significance: it determines whether exact recovery of the correspondence between database entries is possible for any algorithm ...
