現今的環境不論是服務或是手續都是講究簡單與迅速,試想相同的事情若是 可以很快且容易的完成,還會有誰想用舊有的方式來慢慢處理呢?這樣的道理放 在每個地方都是適用的,而且在企業方面更是顯著,不管是在提供客戶服務來爭 取客源或是整合企業內部流程來提升競爭力都是相同的道理,所以企業紛紛投入 資金與人力在這方面,而成效最大的莫過於建置資訊系統來處理繁瑣、複雜而且 重複率又高的工作。 當然,系統建置不是一件簡單的事,這需要許多的準備工作,首要就是先界 定系統的定位,瞭解系統要做那方面的應用,它要能達到什麼要求和能提供什麼 服務等等,再來就是選定要使用那一種技術來實作我們的系統;因此,選擇適合 的技術來開發系統是重要的一件事。本論文研究的方向便在於如何正確地選擇並 使用技術來建置系統。在此,我們提出了JavaBeans 與Enterprise JavaBeans 兩種 元件式資訊系統開發技術,這兩者在名稱上有些類似,但卻是兩種完全不同的架 構,且在不一樣的環境裡能展現出各自擅長的部份。我們可以利用這兩種技術來 完成不同功能的系統來符合我們的需求。 此外,本論文也以晶圓代工下單系統與進銷存系統兩個系統為例,說明如何 將作業流程做分析、規劃,再依照JavaBeans 元件式資訊系統開發技術與 Enterprise JavaBeans 元件式資訊系統開發技術實際開發一元件式資訊系統。
In this time, everything needs the dealing with convenience and efficiency. In particular, enterprises need to provide good and convenient service to the customer for maintaining good customer relation. Therefore, enterprises spend a lot of money to build up computer systems for attaining these purposes. It is a hard job to establish a system. It has much preparatory work to do. The first is to understand what we want the system to do, and what service the system can provide. The second is to choose an appropriate technology to build up the system. Therefore, choosing the right technology is a very important thing for developing the system. In this paper, we study "JavaBeans" and "Enterprise JavaBeans" component base technology for developing the system. They are two completely different technology and they can achieve the different function in different environments. By using these two technology, we can accomplish systems have different function to satisfy to our demand. On the other hand, we give Total Customer Engineering Service System and Logistics System for our case study. We do system analysis, system design and using "JavaBeans" and "Enterprise JavaBeans" component base technology for developing the system.
