LHC Databases on the Grid: Achievements and Open Issues [PDF]
arXiv, 2010 To extract physics results from the recorded data, the LHC experiments are using Grid computing infrastructure. The event data processing on the Grid requires scalable access to non-event data (detector conditions, calibrations, etc.) stored in relational databases.

Is Distributed Database Evaluation Cloud-Ready? [PDF]
, 2017 The database landscape has significantly evolved over the last decade as cloud computing enables to run distributed databases on virtually unlimited cloud resources. Hence, the already non-trivial task of selecting and deploying a distributed database system becomes more challenging. Database evaluation frameworks aim at easing this task by guiding the

Coded Data Rebalancing: Fundamental Limits and Constructions [PDF]
arXiv, 2020 Distributed databases often suffer unequal distribution of data among storage nodes, which is known as `data skew'. Data skew arises from a number of causes such as removal of existing storage nodes and addition of new empty nodes to the database. Data skew leads to performance degradations and \textcolor{black}{thus} necessitates `rebalancing' at ...

Security Implications of Distributed Database Management System Models [PDF]
arXiv, 2014 Security features must be addressed when escalating a distributed database. The choice between the object oriented and the relational data model, several factors should be considered. The most important of these factors are single and multilevel access controls (MAC), protection and integrity maintenance.
