21. A major goal for distributed concurrency control is distributed serializability ( or global serializability for multidatabase systems ). 22. A major goal for distributed concurrency control is distributed serializability ( or global serializability for multidatabase systems ). 23. Only cycles of ( only ) materialized conflicts are also cycles of the regular conflict graph and affect serializability . 24. Breaking the global cycle in the global conflict graph ensures that both global CO and global serializability are maintained. 25. (Note that the first two bullet points here match serializability : the operations appear to happen in some order. 26. MVCC can be combined with all the serializability techniques listed above ( except SerializableSI which is originally MVCC based ). 27. "' Serializability theory "'provides the formal framework to reason about and analyze serializability and its techniques. 28. "' Serializability theory "'provides the formal framework to reason about and analyze serializability and its techniques. 29. This results in both distributed CO compliance ( and thus distributed serializability ) and automatic global ( voting ) deadlock resolution. 30. That serializability makes it more manageable than a tree of items which must be visted, one article at a time.
