網際網路超媒體資料庫工作量模型產生之研究 / Web-Based Hypermedia Database Benchmark Workload Development林嬿芳, Lin, Yen-Fang Unknown Date (has links)
網際網路超媒體資訊系統讓使用者能透過各種媒體共享資訊。每個超媒體資訊系統都擁有其後端資料庫。超媒體資料庫是用來儲存各種形式的資料。在近幾年來,超媒體資料庫有愈來愈多的趨勢。但我們無法知道哪種超媒體資料庫的績效較佳。績效評估是個重要的工具,它可以用來衡量和評估超媒體資料庫的效能。現今有許多績效評估的工作量模型可用來測試一般的資料庫,但卻沒有適合用來測試超媒體資料庫的工作量模型。在這情況下,我們發展了更一般化、由四個元件組成的工作量模型,用來作超媒體資料庫的績效評估。這四個元件分別為物件模型(Object Model)、應用模型(Application Model)、導覽模型(Navigation Model)及控制模型(Control Model)。每一個元件是用來建立每一面向的超媒體資料庫工作量需求。之後,我們建立此工作量模型的系統雛形,以證明此超媒體工作量模型是可行的。發展此正規且系統化的工作量方法可以幫助使用者預測及表示超媒體資料庫系統的績效。最後我們討論並解釋我們的工作量模型及和其它物件導向資料庫績效評估的關係。 / Web-based Hypermedia information systems (WHIS) enable users to share the information through a variety of media. Every Hypermedia information system has its own backend databases. The Hypermedia database is used to store a variety of data. Hypermedia databases are created more and more in the recent years. But we cannot find out which Hypermedia database provides higher performance. Benchmark gives a vital tool to measure and evaluate the performance of the Hypermedia databases. There are many benchmark workload models used to test the general databases. However, there is few benchmark workload model to test the Hypermedia databases. With this scenario, we have developed a more generalized four-component workload model for Hypermedia database benchmark. These components are the object model, the application model, the navigation model, and the control model. Each models one key aspect of the Hypermedia database workload requirements. And then, we build the prototype of this workload model to showht the Hypermedia benchmark workload model is feasible. A formal and systematic workload method is developed that can help users predict and profile the performance of the Hypermedia databases. Finally, we discuss and explain our workload model and the relationships with other object-oriented database benchmarks.
