  3. Combining with java and xml, the designing of xml database, and, the mapping modes between xml and relational database, and the issue of java xml data binding are studied. in addition, uml is applied in designing process of xml schema and documents, which provides us an approach in solving problems that faced by xml application, and can simplify the exploitation of xml application

    結合java語言和xml的特點，研究了xml數據庫的設計以及xml與關系型數據庫之間的映射模式，還有java和xml的數據綁定問題，並且將uml應用到xml模式和文檔的設計過程當中，為解決xml應用中所必須面對的問題提供了一種途徑，可以簡化和規范xml應用的開發過程。
  4. It is a feasible way to manager spatial objects by utilizing relational database in the gis applications. we have brought to octa - tree index structure for managering spatial data efficiently in relational schema. by space filling curve, z - curve, we mapped rsdd to 1 - dimensional linear sp

    為了在關系模式下有效地對空間數據進行處理，論文提出了八分樹的索引結構，並利用空間填充z一曲線把rsdd空間映射到一維空間，從而建立起了空間對象的索引順序。
  5. We have tried to keep the purchase order table schema simple in the relational - only database by storing the purchase order document as a blob

    我們已經通過將采購訂單文檔存儲為blob ，在基本關系數據庫中盡量保持采購訂單表模式簡單。
  6. This dissertation studies the issues on xml storage, updating and retrival in rdbms. in particular, it focuses on the problems of adaptation of xml storage schema, normalized storage of xml, constraint - preserving xml updating, the efficient retrieval of xml data and the optimal path index selection of xml, etc. various new algorithms and techniques are proposed and implemented in an xml - relational database system prototype

    本文研究基於關系數據庫的xml數據的存儲、更新和檢索技術，對xml數據的存儲模式優化調整、 xml數據的規范化存儲、 xml數據保持健約束的更新、 xml數據檢索技術、基於代價的路徑索引構建等方面進行了深入的研究和探討，提出了有效的演算法和新的技術。
  7. Specially, we have researched the topological relation between ros and the measurement of ros. object - relational database technique is a mature database technique, in the chapter 4, we have investigated the technology that using relational schema manager spatial objects, and given a general method or strategy

    對象關系數據庫是較為成熟的數據庫技術，我們在第四章中研究了利用對象關系數據庫處理空間對象的技術，給出了在關系模式中處理空間對象的一般思路和方法，為地理信息系統的有效應用提出了一種切實可行的辦法。
  8. When you design your dimensions and cubes by using the top - down method in business intelligence development studio, you create dimension and cube definitions in a microsoft sql server 2005 analysis services ssas project and then use the schema generation wizard to generate a data source view, a data source, and the underlying relational database schema that supports these olap objects

    Microsoft sql server 2005 analysis services （ ssas ）提供兩種方法來設計和生成analysis services數據庫：由下至上方法-從現有的關系數據庫開始，創建一個基於關系數據庫架構的數據源視圖，然後使用sql server設計工具和向導創建基於該數據源視圖的analysis services維度和多維數據集。
  9. To persistence the objects there are two common approach. one approach is that structured query language ( sql ) codeis embedded in the source code of your classes. the other approach is that sql statements for your business classes are encapsulated in one or more " data classes. " the disadvantage is that it directly couples your business classes with the schema of your relational database, implying that a simple change such as renaming a column or porting to another database results in a rework of your source code

    實現在關系數據庫存取對象，常用的做法有：一種方法是在對象中直接編寫sql代碼來存取對象，另一種方法是將sql代碼在專門的數據類（或存儲過程）中編寫，但著兩種方式都使得對象模型與關系數據庫模式的耦合度大，不容易維護，因為關系數據庫模式的微小改動，都將導致應用程序的重新編譯。
  10. To represent a relational database schema that is mapped to an ejb design

    的xml文件來表示映射到ejb設計的關系數據庫模式。
  11. Elements in the ejb dd should be mapped to the fields in the relational database schema

    元素應如何映射到關系數據庫模式中的欄位。
  12. So why were the relational database schema center and so many other database - related plug - ins activated

    而為什麼關系數據庫模式中心（ 6 ）和那麼多其他數據庫相關的插件被激活了？
  13. Whereas most orm solutions map a class to a relational database schema, hybrid frameworks like ibatis map classes to the result of an sql query

    大多數的orm解決方案把一個類映射到一個關系數據庫模式，而諸如ibatis之類的混合框架則把類映射到一個sql查詢的結果。
  14. Finally, two application components to the conversion between relational schema and xml schema are builded, and an uniformed tool for conversion among heterogeneous relational database systems is developped

    最後就關系模式與xml的轉換建立了兩個應用組件，並開發出了異構關系數據統一轉換工具。
