A rule mechanism for an object - relational database management system 關系模型的規則機制
On the implementation methods of object - relational database 對象關系數據庫系統實現方法的研究
Xml storage techniques in object - relational databases 很多現代關系數據庫管理系統對其產品進行擴展以支持
Your persistence layer , an object - relational database , includes familiar abstractions like 持久層是一個對象關系數據庫,它包括像
As a large scale object - relational database management system , oscar also provides these two methods 作為一種大型的對象關系型數據庫管理系統, oscar也采用了這兩種方法。
The index structure of an object - relational database must be extensible because its type system is 對象關系數據庫中的數據類型是可擴展的,與此相關的索引結構也應當能夠擴展。
Db2 udb is an object - relational database server that provides a solid foundation to achieve high performance and scalability Db2 udb是一個對象-關系數據庫服務器,為取得高性能和可伸縮性提供了堅實的基礎。
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。
Our vision is to manager 3d spatial objects by relational database management system and to manipulate the 0 - dimensional object , 1 - dimensional , 2 - dimensional , and 3 - dimensional in unifiable manner . we employ the mature technology of object - relational database in existence to solve some complex problems of spatial operations efficiently 研究中,我們把三維空間中的0維對象、 1維對象、 2維對象和3維對象納入了統一的處理框架,為利用現有的數據庫技術處理復雜的地理數據探索出一條可行的途徑。
In the past 30 years , the database system has already developed the no relational model , the next generation object - relational database system ( ordbs ) , the third generation object oriented database system ( oodbs ) . in the 1990s later , for the speed of the internet technique , the website base based on the internet promoted the information resource share 經過30年的發展,數據庫系統已經歷了第一非關系型數據庫、第二代關系型數據庫( ordbs )的發展到面向對象數據庫系統( oodbs )和各種專業數據庫。九十年代后由于互聯網絡技術的飛速發展,基于互聯網的網站數據庫技術為信息資源的共享提供了技術上的保障。
