- Contains the information about how an entity, attribute, role, or inheritance binds to a physical data source. 包含有關(guān)如何將實(shí)體、屬性、角色或繼承綁定到物理數據源的信息。
- Buffer Cache Memory allocated for storing data blocks read from physical data files. 緩沖區緩存為存儲從物理數據文件讀取的數據塊而分配的內存。
- This separation of access criteria from physical storage characteristics is called physical data independence. 從物理存儲特征中分離出訪(fǎng)問(wèn)標準叫作物理數據獨立性。
- All you need to do is to generate the physical data model that corresponds to your conceptual data model. 唯一還需要做的事情就是生成與概念數據模型相對應的物理數據模型。
- The name of the column in the physical data source to which the entity or attribute is bound. 物理數據源中要與實(shí)體或屬性綁定的列的名稱(chēng)。
- DIU receives and sends serial data. C/DSU changes the format of serial data and matches the physical data link. DIU完成據串行接口的功能,C/DSU完成數據幀傳輸的格式轉換和鏈路匹配的功能,同時(shí)實(shí)現了端口的復用和擴展。
- The SQL Server 2005 Database Engine sets file access permissions on the physical data and log files of each database to specific accounts. SQL Server 2005數據庫引擎為特定帳戶(hù)設置了對每個(gè)數據庫中的物理數據和日志文件的文件訪(fǎng)問(wèn)權限。
- The abstract methods deal specifically with saving and loading data to a physical data store, and with data store administration. 這些抽象方法專(zhuān)門(mén)處理在物理數據存儲區中的數據保存、數據加載和數據存儲區管理。
- The virtual Binding object contains the information about how an Entity, Attribute, Role, or Inheritance object binds to a physical data source. 虛擬的Binding對象包含如何將Entity、Attribute、Role或Inheritance對象綁定到物理數據源上的信息。
- The data model about management and application of machine tool based on Erwin software is built. A method to achieve physical data library is given. 利用Erwin軟件對加工中心刀具管理與應用進(jìn)行了數據建模 ,給出了獲得物理數據庫的方法
- Searchable database of over 1300 hazardous chemicals. Includes names, synonyms, formula, physical data, NFPA ratings, DOT guides and registry numbers. 超過(guò)1,300種危險化學(xué)品的資料庫,包含名稱(chēng)、符號、化學(xué)式、物性資料、NFPA分級、毒性程度。
- Since the responsibility for accessing the physical data rests with the database management system, the programmer can ignore the physical data structure. 由于存取實(shí)際數據的責任由數據庫系統承擔,因此程序員就可不考慮實(shí)際的數據結構,導致了程序更少地依賴(lài)于它的數據,
- Whereas the conceptual model is largely independent of implementation details, the physical data model is tightly bound to the table structure and options available in a particular database application. 雖然概念模型在很大程度上獨立于實(shí)施細節,但物理數據模型與特定數據庫應用程序中的表結構和可用選項緊密相關(guān)。
- The insulation layer is extremely important to SOA because it allows transparency of database vendor products, OS platforms, information location, data format, and a physical data model. 這種隔離層對于SOA來(lái)說(shuō)非常重要,這是因為它使得數據庫廠(chǎng)商的產(chǎn)品、OS平臺、信息位置、數據格式以及物理數據模型透明化。
