Towards a visually interpretable analysis of Two-Phase Locking membership
Davide Martinenghi
Two-phase locking (2PL) is a consolidated policy commonly adopted by Database Management Systems to enforce serializability of a schedule. While the policy is well understood, both…
Partitioning Strategies for Parallel Computation of Flexible Skylines
Emilio De Lorenzis, Davide Martinenghi
While classical skyline queries identify interesting data within large datasets, flexible skylines introduce preferences through constraints on attribute weights, and further reduc…
Simplified integrity checking for an expressive class of denial constraints
Davide Martinenghi
Data integrity is crucial for ensuring data correctness and quality, maintained through integrity constraints that must be continuously checked, especially in data-intensive system…
Computing the Non-Dominated Flexible Skyline in Vertically Distributed Datasets with No Random Access
Davide Martinenghi
In today's data-driven world, algorithms operating with vertically distributed datasets are crucial due to the increasing prevalence of large-scale, decentralized data storage. The…
