- 中文摘要: 一個多媒體資料庫管理系統管理任意由文字、影像、動畫、聲音及影片組合成的資料。由於不同的資料型別的複雜組合及多媒體應用程式的許多特性,故傳統以欄位為基礎的DBMS並不能提供足夠的效率及功能來滿足多媒體之應用。在這篇論文中,我們設計及製作一個QBOE(Query-By-Object-Example)以物件為基礎的多媒體資料庫系統查詢語言。我們的查詢語言稱為Query-By-Object-Example,因為無論資料定義語言(DDL: Data Definition Language)及資料處理語言(DML: Data Manipulation Language)皆藉由一個範例進行。在DDL的部份,使用者可以指定多媒體應用的雛形,包括對此應用的關鍵字及相對所需之運作。在DML的部份,使用者可藉由資料中的關鍵字及一些指定特性的內容來擷取所需資料。
- 英文摘要: A multimedia database (denoted as MMDB) management system manages multimedia data, wheremultimedia data is defined as any combination of data in the form of text, images, animation, sound andvideo. Due to these complex combinations of different types of data, and many special properties ofmultimedia applications, traditional record-based DBMS techniques are neither effective nor powerfulenough to support them. In this paper, we design and implement a QBOE (Query-By-Object-Example)query language for multimedia database systems. Our system is based on an object-oriented model. Thequery language is called Query-By-Object-Example since either DDL (Data Definition Language) or DML(Data Manipulation Language) is used as an object example. In the DDL part, the user can specify theprototype of a multimedia application, including specific keywords for the application and related op-erations. In the DML part, the user can access data by means of contents or keywords which are specifiedin attributes.
