In this paper, we introduce Quasi Serializability, a correctness criterion for concurrency control in heterogeneous distributed database environments. A global history is quasi se...
We give a new view on building content clusters from page pair models. We measure the heuristic importance within every two pages by computing the distance of their accessed positi...
