您要查找的是不是:
- Replication requires a persistent logical database name. 複製需要一個持久的資料庫邏輯名稱。
- Size check done against the database now uses logical database size. 現在使用邏輯資料庫大小對資料庫進行大小檢查。
- A poor logical database design can hinder the performance of the whole system. 邏輯資料庫設計不好,會影響整個系統的性能。
- Any Transact-SQL code that contains logical database names will not work. 任何包含資料庫邏輯名稱的Transact-SQL代碼都無法使用。
- If the logical database size exceeds the maximum size limit, it will be dismounted on a regular basis. 如果資料庫邏輯大小超出大小上限,則會被定期卸除。
- Event ID 9688 indicates that you have reached the threshold you have configured for maximum logical database size. 事件ID 9688指示您已達到了為最大邏輯資料庫大小配置的閾值。
- Sometimes, the logical database design is already fixed and total redesign is not realistic. 有時,邏輯資料庫設計已經固定,全部進行重新設計是不現實的。
- Normalizing a logical database design involves using formal methods to separate the data into multiple, related tables. 規範化邏輯資料庫設計包括使用正規的方法來將數據分為多個相關的表。
- A good logical database design can lay the foundation for optimal database and application performance. 設計好邏輯資料庫,可以為優化資料庫和應用程序性能打下基礎。

- By default, the threshold for logging a warning event is when 90 percent of the maximum logical database size is consumed. 在默認情況下,記錄警告事件的閾值是,當消耗了最大邏輯資料庫大小的90%25時。
- By default, the threshold for logging this warning event is when 90 percent of the maximum logical database size is consumed. 默認情況下,記錄此警告事件的閾值是佔用了90%25的最大邏輯資料庫大小。
- 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. 因為資料庫的邏輯名稱取決於文件位置,該位置會在每次Xcopy時發生更改,所以,任何指定資料庫邏輯名稱的代碼都無法使用。
- 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. 如果完整路徑和文件名的長度超過127個字元,則需要縮短資料庫的邏輯名稱,並且加上前綴GUID,從而確保邏輯名稱的唯一性。
- 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. 資料庫的下一層邏輯結構是「範圍」(或者稱為"區"),範圍是有若干個連續的由於存儲特定信息的數據快組成。
- It was taking all of those databases and creating a logical database that you could connect to through rich Web services. 它正在帶所有的那些資料庫而且創造一個你可以連接到穿越富有的網路服務的合乎邏輯的資料庫。
- 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]. 然後;就自頂向下方式的性能是否一定優於自底向上方式;以及理想的邏輯資料庫事物間聯繫的狀態是否應當沒有迴路問題提出不同的看法;與文[1]的作者商榷.
- Oxygen enters into many compound bodies. 氧是許多化合物的組成部分。
- Air is a mixture, not a compound of gases. 空氣是氣體的混合物,不是化合物。
