Why might B-tree concurrency control still be interesting? For two reasons: (i) currently exploited "real world" approaches are complicated; (ii) simpler proposals are n...
We advocate the use of agents to model a system that allows us to integrate and protect information stored in both mobile and fixed devices, while trying to preserve a consistent a...
In a recent study, we have shown that in real-time database systems that discard late transactions, optimistic concurrency control outperforms locking. Although the optimistic alg...
