設計一個多媒體資料庫管理系統上的物件管理與查詢系統

Abstract

由於電腦軟硬體的不斷進步，促使電腦多媒體成為九十年代的新寵。多媒 體除了能適用於傳統的應用系統，更適用於各種新興的應用，如：醫療診 斷、天氣預報及教育訓練等，以及目前政府正大力推行國基資訊基礎建設 (NII) 上的各種應用如隨選視訊，電子購物，遠距教學。這些應用需建構 在適當的使用與管理的系統上，才能有事半功倍的成效。以往多媒體資料 大多利用檔案系統存取，應用軟體必須自行管理資料的存取與使用，必須 瞭解細部的操作方式才能完成。多媒體資料庫系統的物件管理提供多媒體 資料的管理與簡易使用界面的工具。本研究便是要發展一套有效的『多媒 体資料庫管理系統上的物件管理與查詢系統』，本系統是一個以視窗為基 礎的圖形環境中提供資料擷取方法，並提出了一套伺服器與客戶端之間透 過訊息傳遞的網路溝通架構。 With the advance of computer hardware and software technology, multimedia systems become the rising topics of computer systems and are very popular during the 90*s. Multimedia systems are not only applied to traditional applications, but also are applied to a variety of infant applications, such as weather forecast, physic diagnosis, amusement, and applications of National Information Infrastructure(NII) like Video in Demand, Home Shopping, Distance Learning. These applications that will be efficient must be constructed on the systems which are able to operate and manage data properly. Using file systems, applications should manage data storage and data access by themselves and need to know the detailed operations. Object management for database systems provides a convenient tool to manage and access data. In this research, we build a prototype of object management and query system for multimedia database systems. Our system is implemented on a window-based grap
