  1. 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。
  2. This radar database system fits for china ' s radar network using object - oriented programming design method, recording some important parameters of radar data : the longitude, latitude of radar station, radar type, radar wavelength, radar data format, weather kind ( kind of intensity radar echo, schema of velocity radar, echo shape ) embodying in the radar data, etc. it also records the weather course information embodying in a series of relational radar data : the beginning time of weather course, the ending time of weather course, weather type, etc and the disk information, including recording time, recording contents, recording data number and weather type, etc. above all, this system realizes some basic operational processing : adding, deletion, updating, query of records and also some assistant functions : exportation, data transformation, displaying, backing up of data

    該數據庫系統採用面向對象程序設計方法，用visualc + + 6 . 0作為應用程序的前端開發工具，用microsoftaccess2000做數據庫，不僅實現了對雷達基數據信息的一些基本操作：記錄信息添加、刪除、修改、查詢，還實現了處理、分析雷達基數據所需的一些操作：數據導出，數據格式轉換、數據回顯（圖像方式和動畫方式） 、數據壓縮、備份等，另外針對日前雷達臺站存儲雷達數據的現狀，還實現了對存儲光盤的管理。
  3. The design of database is based on the theory of relational database system. the ways of maintaining integrality of database and using transaction in multiple table access to guarantee the consistency and recoverability of database are discussed in the thesis

    以關系數據庫系統理論為基礎進行了數據庫設計，並討論了保證數據完整性、在多數據表操作中應用事務處理等問題。
  4. Developing of the system including argumentation of feasibility and systematic analysis, design of relational database and firstly design of system models. the whole developing procedure is disparted to about seven building phrases : system model designing, system detail designing, the first code programming, the first checking and accepting and tryout, code maintenancing and upgrading, system maintenance

    本系統的開發經歷了項目可行性論證與系統分析，關系數據庫設計和系統功能模塊初步設計，整個開發過程分為系統功能模塊設計，系統詳細設計，第一期程序編碼、第一期驗收及試運行，代碼維護和升級，系統維護等七個開發四川大學碩士學位論文階段。
  5. With the union of uml modeling and relational database designing, a set of mapping method of database design named object - relationship is presented in the paper, which is used in a e - business system, improving the designing of database

    摘要將uml類圖模型與關系數據庫設計相結合，利用面向對象方法和工具提出一套完整的對象關系映射方法，應用於電子商務系統，加速了系統數據庫的設計。
