最近幾年來，網際網路的出現及應用面的廣泛，改變了企業的資訊架構。從Client/Server擴展到以Web為應用程式的平台，企業面臨了資訊架構的重整，企業網路、電子商務都是現今最新的應用。由於全球資訊網採開放架構，並以HTML、HTTP為標準，使得資訊業者有所依循，開發出許多產品來滿足企業的需求。隨著Web的廣泛使用，應用程式架構、介面與行為特質都將與以往有著大大的不同，元件及交易導向的Web應用程式是勢在必行的路。 對此變革，企業最重要的課題之一是，如何建構完整的企業網路環境以增強競爭力。資料庫系統是企業各種資訊軟體的基礎，在以Web為應用程式的平台的架構下，它仍是其中重要的關鍵元件。選擇資料庫系統必須考慮許多因素，而且現有的資料庫系統的產品很多，各項產品的特性與優點均有不同，每一種產品甚至可再細分成許多元件，可依照需要選用，因此資料庫產品的選擇變成一種複雜的過程。若選擇錯誤則不僅是金錢耗費的損失，更深遠地影響整個企業的順利運作，甚至是企業競爭力的下降，更可能嚴重到影響企業的存續。故資料庫系統的選擇不可不慎。 本文提出一網際網路資料庫體系選擇模式，協助企業在全球資訊網的開放架構及多階層應用系統環境下，評選出符合企業本身狀況及需求的網際網路資料庫系統。此模式內容包含，需求分析與確認、第一至四級網際網路資料庫體系需求屬性之彙整、兩階段的廠商篩選及含加權機制之廠商評比。 最後並將此模式運用於，行政院衛生署藥物食品檢驗局之購置網際網路資料庫設備計劃。 / Internet technology has drastically changed the enterprise computing and platform. Database management and systems represent the core of the change and the key of the new revolution of the information technology and infrastructure. Business information and models have been stored and manipulated through the use of the database technology. Due to the fast growing speed and variety of the database products in the marketplace, managers are having difficult making the right decision in selecting and maintaining the Internet database management and systems. To tackle this issue, we propose a requirements-based software selection model from the user’s viewpoint. In this research, we develop a five-step choice model with an emphasis on the requirement analysis and rank analysis. We collect and compile the functional and non-functional characteristics and features of the Internet database management and systems. We classify and organize them into a four-layer hierarchy and work with the weight mechanism in the rank analysis. This choice model adopts another five-part rank policy in order to produce the final suggestion of software selection. In the end, we apply the new model in a field case study of the Web Database Systems Procurement Project with the National Laboratories of Foods and Drugs, Department of Health, Executive Yuan.

網路開放商業化以來，各式各樣的商機在網際網路上浮現，大小商家紛在網路上設立據點，或從事廣告、宣傳公司形象，或展示產品內容與產品功能，有的更進一步的設計能與消費者在網路上直接交易，我們概括性的稱之為電子商務。在電子商務的背後，各網站必須要有資料庫作支撐，才能有好的效率和服務。本研究以網際網路資料庫為探討主體，績效為探討目的。並主要以績效評估(Benchmark)理論為貫穿整個研究的基礎理論，一步步地建立適合網際網路資料庫及運算作績效評估的模型。並於模型完成後，予以程式化實作，並以所得數據作測試。 / A lot of business opportunity springs after commercial activities are officially allowed on Internet. The power and the potential of this market is represented by lots of web sites being set up. "Electronic Commerce" is coming to the whole world. However, it is the database supporting business web sites running that counts. Based upon the theory of benchmarking, we want to find out ways that we can know the performance of web database. After the model is set up and the workload is ready, an implementation is being made.

With the prevalence of internet, it is gradually becoming a trend to use the network as a tool of computer-added education. However, it is used to present the computer-added education with static state of the word, but it is just convenient to read for the user and there are no difference with traditional textbook. As the growing up of WWW and the development of Java, the interactive computer-added education is becoming a trend in the future and it can promote the effect of teaching basic statistics with the application of this new media. The instructor can take advantage of HTML by combining with Java Applets to achieve the display of interactive education through WWW. In this paper, we will use six examples of Java Applets about statistical computer-added education to help student easily to learn and to understand some abstract statistical concepts. The key methods to reach the goal are visualization and simulation with the display of graphics or games. Finally, we will discuss how to use the Applets and how to add the Java Applets into your homepage easily.

Atualmente, o use de ferramentas de apoio ao projeto de circuitos integrados é indispensável, devido a complexidade desses circuitos que aumenta incessantemente. O presente trabalho discute um modelo para integração de ferramentas em um ambiente único - formando um framework - com o objetivo de acelerar o processo de concepção dos circuitos através da automatização de tarefas, livrando o projetista de tarefas como a administração de recursos distribuídos, o armazenamento de arquivos e assim por diante. 0 framework proposto é baseado em um ambiente amplamente conhecido: o World Wide Web. Ao utilizar o World Wide Web como base para o ambiente de integração de ferramentas, muito trabalho é poupado, uma vez que grande parte da interface gráfica e do controle de rede do framework já esta implementada. A facilidade de acesso ao WWW também é uma grande vantagem, no caso de uma equipe de projeto distribuída. A integração das ferramentas segue dois modelos. O primeiro é utilizado em ferramentas de maior interação com o usuário. Nesse caso, a ferramenta deve ser re-escrita para ser integrada ao ambiente na forma de applets - programas escritos com a linguagem Java que podem ser anexados a documentos WWW. O segundo modelo é utilizado em ferramentas com pouca ou nenhuma interação com o usuário. Essas ferramentas são integradas através de entradas e saídas de dados. Usando applets Java, a funcionalidade e a interface gráfica da ferramenta são independentes de plataforma e podem ser anexadas a documentos WWW, o que faz com que a ferramenta possa ser executada na maquina do projetista. reduzindo a carga de processamento do servidor do framework. Já as ferramentas integradas usando o segundo modelo devem ser executadas no servidor devido compatibilidade, já que são dependentes de plataforma. Objetivando fundamentar e validar a proposta do framework baseado no WWW, uma revisão bibliográfica é apresentada, em ambos os temas: World Wide Web e CAD Frameworks. A partir dessa revisão e da especificação proposta, implementou-se um protótipo integrando ferramentas usando ambos os mecanismos descritos. A descrição do protótipo e suas características são apresentadas, bem como alguns pontos críticos que devem ser alvo de pesquisa em trabalhos futuros. / Nowadays the use of design automation tools for integrated circuits is more necessary than ever, due to the always increasing complexity of such circuits. This work discusses a model for tool integration in a framework, in order to speed up the design flow, saving the designer from tasks such as distributed resources and file administration. This framework is based on a well known environment: the World Wide Web. When using the World Wide Web as the base for the framework, a lot of work is saved since most of the user's graphic interface and the network management is already done. The availability of the WWW is also interesting, in the case of a distributed design team. The integration of the tools follows two models. The first is that of interactive tools. In this case, the tool must be re-written to be integrated to the environment as applets - applications written using the Java language that can be attached to WWW documents. The second model is used on poorly or non-interactive tools. In this case, the tool is integrated by its input and output streams. Using Java applets, the tools functionality and graphical interface are platform independent and may be attached to a WWW hyperdocument. Thus, the tool may run at the user's machine. Using this architecture, it is possible to divide the processing task among the framework server and the designer's machines. The tools that are integrated using the second model must run on the framework server due to compatibility issues, since they are platform dependent. In order to validate the proposed web based design framework, a literature review is presented in both themes: World Wide Web and CAD Frameworks. From the literature review and the proposed specification, a prototype was implemented, integrating tools using both the mechanisms described. The description of the prototype and its features are presented, as well as some critical points that need to be improved in future works.
