serializability meaning in English
可串行化
Examples
- Is a schema stability sch - s lock . in this case , serializability is no longer guaranteed
唯一采用的锁是架构稳定性锁（ sch - s锁） 。 - Serializability may not be implemented using only row - level locks ; there must be another mechanism that prevents a newly inserted row from becoming visible to a transaction that has already executed a query that would return the row
如果仅仅通过“行级锁”是无法实现事务序列化的，必须通过其他机制保证新插入的数据不会被刚执行查询操作的事务访问到。 - This is referred to as serializability because it results in the ability to reload the starting data and replay a series of transactions to end up with the data in the same state it was in after the original transactions were performed
这称为可串行性，因为它能够重新装载起始数据，并且重播一系列事务，以使数据结束时的状态与原始事务执行的状态相同。 - But at present , there seem to be much deficiencies on the correctness and reliability of workflow and it can not meet the practical needs very well . in this paper , we introduce some transactional properties to workflow and put forward a nested workflow model with transactional characteristics . this model includes nested tasks and dependencies between the tasks , and it is provided with some atm properties such as relaxed isolation and atomicity . further more , we discuss the execution mechanism , system recovery and error handling of workflow on the base of the transactional characteristics . by defining consistency unit and execution atomic unit , we loosen the failure atomicity , serializability of concurrent worflow and isolation between tasks , thus , workflow meets the needs of the application semantics more flexiblly with high correctness and reliability
这个模型包含嵌套任务和任务间的依赖，并具有高级事务模型的一些属性，比如松散的隔离性和原子性。我们又进一步在这个模型的基础上利用这些事务性质提出了有关工作流的执行机制、系统恢复和错误处理等问题的解决方法。通过定义一致性单元和执行单元放松了事务的失败原子性、并发工作流的可串行化要求以及任务间的隔离性，使工作流在具有高可靠性和正确性的前提下更灵活地满足实际应用语义的要求。
