您要查找的是不是:
- Replication requires a persistent logical database name. 复制需要一个持久的数据库逻辑名称。
- Size check done against the database now uses logical database size. 现在使用逻辑数据库大小对数据库进行大小检查。
- A poor logical database design can hinder the performance of the whole system. 逻辑数据库设计不好,会影响整个系统的性能。
- Any Transact-SQL code that contains logical database names will not work. 任何包含数据库逻辑名称的Transact-SQL代码都无法使用。
- If the logical database size exceeds the maximum size limit, it will be dismounted on a regular basis. 如果数据库逻辑大小超出大小上限,则会被定期卸除。
- Event ID 9688 indicates that you have reached the threshold you have configured for maximum logical database size. 事件ID 9688指示您已达到了为最大逻辑数据库大小配置的阈值。
- Sometimes, the logical database design is already fixed and total redesign is not realistic. 有时,逻辑数据库设计已经固定,全部进行重新设计是不现实的。
- Normalizing a logical database design involves using formal methods to separate the data into multiple, related tables. 规范化逻辑数据库设计包括使用正规的方法来将数据分为多个相关的表。
- A good logical database design can lay the foundation for optimal database and application performance. 设计好逻辑数据库,可以为优化数据库和应用程序性能打下基础。

- By default, the threshold for logging a warning event is when 90 percent of the maximum logical database size is consumed. 在默认情况下,记录警告事件的阈值是,当消耗了最大逻辑数据库大小的90%25时。
- By default, the threshold for logging this warning event is when 90 percent of the maximum logical database size is consumed. 默认情况下,记录此警告事件的阈值是占用了90%25的最大逻辑数据库大小。
- Because the logical name of the database depends on the file location, which will change with each Xcopy, any code that specifies a logical database name will fail. 因为数据库的逻辑名称取决于文件位置,该位置会在每次Xcopy时发生更改,所以,任何指定数据库逻辑名称的代码都无法使用。
- If the length of the full path and file name exceeds 127 characters, the logical database name is shortened and prefixed with a GUID, ensuring a unique logical name. 如果完整路径和文件名的长度超过127个字符,则需要缩短数据库的逻辑名称,并且加上前缀GUID,从而确保逻辑名称的唯一性。
- The next level of logical database space is an extent. An extent is a specific number of contiguous data blocks allocated for storing a specific type of information. 数据库的下一层逻辑结构是“范围”(或者称为"区"),范围是有若干个连续的由于存储特定信息的数据快组成。
- It was taking all of those databases and creating a logical database that you could connect to through rich Web services. 它正在带所有的那些数据库而且创造一个你可以连接到穿越富有的网络服务的合乎逻辑的数据库。
- Then, a different opinion about whether top-down is naturally better than bottom-up and whether EDB relations in a logic database should be acyclic is put forward to discuss with the authors of [1]. 然后;就自顶向下方式的性能是否一定优于自底向上方式;以及理想的逻辑数据库事物间联系的状态是否应当没有回路问题提出不同的看法;与文[1]的作者商榷.
- Oxygen enters into many compound bodies. 氧是许多化合物的组成部分。
- Air is a mixture, not a compound of gases. 空气是气体的混合物,不是化合物。
