In this research, the authors design and implement a new mechanism to store shared data
(context data) across several sessions in a World Wide Web (hereafter Web) system. The Web
is being used more and more in client-server system architecture, and this trend is continuing.
However, in a client-server system that uses a Web system, problems that did not occur on
conventional client-server systems (those that do not use the Web) occur. One of these is
storing context data. The HTTP (HyperText Transfer Protocol) protocol used in a Web system
is a session, and as a result context data cannot be preserved. Although several mechanisms
to store the context data have been proposed, each has problems with security and reliability.
The authors have decided to use the so-called document view architecture in order to design
a new context data storage mechanism to resolve these problems. This architecture provides
the primary functions needed to store context data. The special characteristic of this new
mechanism is found in storing context data in main memory on the client computer. In
addition, the authors decided to introduce component-object technology to improve efficiency.
This allows for a significant increase in security and reliability. Finally, the authors demonstrate
the validity of their new context data storage mechanism using common applications.

本研究では,World Wide Web(以下Webと呼ぶ)システムにおいて複数のセッション間で
共有すべきデータ(コンテクストデータ)を保持するための新たな機構の設計と実装を行う.
クライアントサーバシステムの構築にWebを採用する場合が増加し,現在ではそれが主流と
なりつつある.一方で,Webシステムを利用したクライアントサーバシステムでは,従来の
(Webを利用しない)クライアントサーバシステムにはなかった問題が発生し得る.その一つが,
コンテクストデータの保持である.Webシステムで用いられるHTTP(HyperText Transfer
Protocol)プロトコルはセッションレスであるため,コンテクストデータの保持ができない.
そのコンテクストデータの保持のための機構が既にいくつか提案されてきているが,
それぞれ安全性や信頼性に関する問題点を抱えている.我々はそれらの問題点を解決する
新たなコンテクストデータストア機構を設計するために,いわゆるドキュメントビューアーキ
テクチャの採用を決定した.このアーキテクチャの上で,コンテクストデータの保持のための
主要な機能を構成した.新しい機構の特徴はコンテクストデータをクライアントコンピュータの
主記憶上に保持することにある.更に,効率性の観点からコンポーネントオブジェクト技術の
導入を決定した.これによって安全性や信頼性を大幅に高めることができる.最後に,典型的な
アプリケーションを想定して,新しいコンテクストデータストア機構の有効性を示す.

We propose a new mechanism for implementing the elec- tronic shopping cart system (shortly, the shopping cart sys- tem) on the World Wide Web system (the Web system). The electronic shopping cart system is one of typical client- server systems, and it includes essential tasks to be imple- mented in the typical Web based client-server system. The most important task is to maintain context data between suc- cessive user sessions.
Although several methods, which can be applied to im- plement the electronic shopping cart on the Web system, have been proposed, any of them can not attain the task of maintaining context data sufficiently. In this paper we analyze the task and point out the following three difficul- ties (d1) reliability, (d2) safety, and (d3) session manage- ment. We then propose a new mechanism (called the Con- text Data Storing (CDS) mechanism) to solve all of (d1), (d2) and (d3). In the proposed CDS mechanism, the context data for the session management is stored in the main memory of the client computer. As a result, the CDS mechanism can achieve both high reliability and high safety as well as the management capability of user sessions.
Next, we use component object technology to implement the CDS mechanism. Then, we compared the performance of the electronic shopping cart system using the proposed CDS mechanism with the one using the previous methods. The result showed that our proposed mechanism has solved all difficulties (d1), (d2) and (d3) and has attained efficient communications between clients and Web servers.
