臺灣博碩士論文加值系統

我們述及了一個欲提供給全球資訊網的資料庫系統。我們的資料庫系統採用以類別代數本體論為雛型所建構出來的資料模型，且據此來儲存及管理物件導向資料。我們的系統為三層式架構，在本篇論文中我們會將重心置於介紹系統中間層的實作。在我們系統的整體架構中，中間層扮演了一個中介者的角色，並且提供了包括使用者管理、連線通訊管理、資料處理、即時更新反應機制等方面的弁遄C

We describe a database system for the World-Wide Web. Our database system can store and manage object-oriented data with the data model which is constructed based on the class algebra ontology. Our system uses a three-tier architecture. In this thesis we mainly introduce the implementation of our system’s middle layer. The middle layer plays an intermediary role in the architecture of our system and it provides the functions of user management, communication management, data processing, and real-time response mechanisms.
