We introduce detailly the its design ideal, merit, purpose and sql language and so on, then we discuss the problem of the design and implement of the v - ordbms. compared with other products, now, v - ordbms, which we are designing, is based on the relational database system for windows os, it extends the abstract data type, such as array, set, structure etc, we solve the store and all sorts of sql operation for these extended data type. otherwise, in v - ordbms, we provide the solution of how to realize the store of class, inherit, and the mapping of the relation among classes. etc. it provides the visual environment for using
對比國外的postgresql ， gemstone ， 02等產品，目前我們設計的v - ordbms原型系統是基於windowsos的平臺，以關系數據庫為基礎，在支持傳統數據類型的基礎上擴展了抽象數據類型adt （ abstractdatatype ） ，例如數組、集合、結構等，解決了它們的存儲以及相應的各種sql操作，能夠支持復雜對象，所以它的數據類型豐富。Aim at special application, this article brings out some data models based on nonstructured engineering data model and use the theory in engineering data model research area for reference, combines the data modeling technology with the object oriented technology, uses the object oriented technology to abstract objects for the application system and abstract the application frame, converts the polymorphism character of the object oriented frame to the complex data storage character, realizes the permanent management of object method hi the object oriented system, and then from the position of data independence, separates the method independent management from the object frame and achieves the polymorphism and extensibility of the object oriented system, fulfills the enterprise application who need customize the software function
本文在非結構化工程數據模型的基礎上，吸取非結構化工程數據模型的研究成果，提出針對專門應用的復雜數據模型，並將數據庫建模技術與面向對象技術相結合，按照面向對象的方法對工程應用進行分析建模，抽取出系統的對象框架結構，將面向對象系統的實現方法作為復雜數據模型處理，實現對象方法的持久化管理，從而在數據獨立性的角度將對象方法從對象框架分離出來單獨管理，在更高的層次上實現了面向對象系統的多態性和可擴展性，滿足了企業復雜應用中對軟體系統進行柔性定製的要求。課題研究的問題為面向對象系統中對象方法的持久化存儲與管理。Wth shared - memory abstract layer, we are able to unite several memory sharing cases including mie sharing in smp, hardware - supported distributed sharing in cc - n ' uma and virtual sharing in clusters. based on this, we discuss and design the logical framwork of paralel and distributed operating systems. one of the key problems in shared - memory management is how to maintain memeory consistency between multiprocessors
針對不同體系結構所呈現出的不同存儲共享的性質，我們提出了一個共享存儲抽象層的概念，用以統一smp等系統中的真共享、 cc - numa等系統中由硬體支持的分佈共享以及工作站機群系統中的虛共享等情況，並在此基礎上探討和設計了并行分佈操作系統的邏輯結構框架。
