数据方面的质量是通过保证数据访问可靠性、数据访问可用性和支持数据存储的并发性与安全性等功能进行判断的。
This ability affects the user interface, business logic, and database; in addition, it is necessary to address issues regarding concurrency, data integrity, user transparency, and replication.
这种能力包括使用用户界面、业务逻辑和数据库的能力；此外，必须解决与并发、数据集成、用户透明度和复制相关的问题。
This concurrency control can greatly reduce timeout situations between readers and writers accessing the same data row.

It must be able to create, participate, or manage transactions while interacting with disparate information systems. This is an absolute must to ensure the concurrency of enterprise data.
它必须能够创建、参与或者管理与不同信息系统之间进行交互时的事务(transaction)，这一点对于保证企业数据的并发性绝对必要。
Mrs. Waldo is accidentally demonstrating a drawback of 2pc: database locks are needed to guarantee isolation and this can have negative consequences for data access (and concurrency).
waldo夫人正意外地展示2pc的缺点：需要数据库锁来保证隔离，但这样可能对数据访问(和并发)有负面影响。
With both CMP and BMP entity beans, the container calls the shots as to when to persist a bean's state and how to ensure data integrity and concurrency with the underlying datastore.
同时使用 CMP和BMP实体bean 时，容器决定何时持续保持bean的状态以及如何确保与底层数据存储的数据完整性和并发性。
Modelers should make no assumptions about the location of the data, call-by-value, or call-by-reference semantics nor any implicit concurrency management facilities.
建模员不应该假设数据的位置，值访问或者引用语义访问，也不应该假设任何清晰的并发管理设备。
Doing so is simply a big headache -- or multiple headaches, rather, with names like multibrowser support, data marshaling, concurrency violation, server load, and custom servlets and servlet filters.
这么做只会带来更大的麻烦（更确切地说，是更多的麻烦），比如多浏览器支持、数据封送处理、并发冲突、服务器负载以及定制servlet和servlet 过滤器。
This section provides details about specific changes made to increase the concurrency of the data loading phase of the RDP Direct Load Asset.
本小节详细讨论提高RDP DirectLoad Asset的数据加载阶段的并发性所需的具体更改。
This addresses the data race, but has further costs for concurrency, since locking the entire list while iterating could block other threads from accessing the list for a long time.
这样做虽然解决了数据争用问题，但是在并发性方面付出了更多的代价，因为在迭代期间锁住整个list会阻塞其他线程，使它们在很长一段时间内不能访问这个列表。
Data partitions increase data change concurrency (no hotspot except the super class) and accordingly OLTP systems usually handle it.
数据分区增加了数据修改的并发性(除了超类，没有热点)，OLTP系统通常会更好些。
Over the past year it has gained a lot of attention, mostly due to its concurrency features such as support for Software Transactional Memory (STM) and other powerful data structures.
过去一年中，它之所以受到广泛关注，最主要的原因是其并发特性，如支持软件事务存储(Soft ware Transactional Memory——STM)及其他强大的数据结构。
Optimistic programming models are best suited for read only data or data that is retrieved, manipulated, and later pushed back to the data source under low data concurrency.
optimistic编程模型最适合只读数据或以后要在并发数少的情况下检索、处理和推回到数据源的数据。
This uses only one lock and keeps others from interfering with the updates, but it does reduce concurrency of the data to other users.
