摘要: 自從Internet商業化的應用蓬勃發展以來,WWW已成為企業內外資訊
流通非常重要的媒體,而大型企業大多已運用網站(Web)技術連上Interne
,並且建構內部的企業網路(Intranet)。然而,大型企業日常營運的資料
絕大部份卻都還是在傳統的資訊系統(Legacy System)上運作,這使得企
業內部形成新舊技術之資訊系統並行,而造成系統與資料難以互通及整合
的問題。因此如何將原有的資訊系統與新的Internet、Intranet及
Extrane整合,是大型企業進行資訊系統整合及發展時最重要也最為困難
之課題。 本研究是針對資訊系統整合之方式加以探討,推導出一個網
站式資訊系統整合模式(Web-Based System Integration Model;簡稱
WBSIM),此模式是運用網站技術,於Internet/Intranet/Extranet之架構
上,以雛型演進法(Prototyping)整合企業之新舊資訊系統,讓企業之客
戶、員工及業務夥伴得到如同單一系統之功能。 本研究並對一大型企
業進行個案研究,探討其資訊系統整合的困難、需求以及其整合之策略。
最後並運用網站式資訊系統整合之模式,以個案公司之資訊環境為藍本,
設計一個整合的初步雛型─全能資訊系統(PIS),以評估網站式資訊系統
整合模式之可用性及其效益。
Ever since the commercial application of the Internet was
rapidly developed, the WWW has become the most important
information medium for the enterprises. Most large-scale
enterprises have connected to the Internet through the
application of Web-based technology and set up their own
internal network (Intranet). However, most of the data in these
enterprises, daily operation are still processed under the
Legacy Information System. Consequently, two types of
information system, based on the old and new technology
respectively, concurrently exist in many enterprises,which led
to the result that the two systems and data can't be mutually
shared and integrated. Thus, it is the most important and
difficult task for large-scale enterprises to integrate the
Legacy Information System with the Internet, Intranet and
Extranet on the purpose of information integration andfurther
development. The Web-Based System Integration Model (WBSIM)
was derived from study probing deep into the methodology on
information system integration. Basedon the Web-based technology
and the Internet/Intranet/Extranet architecture, this model is
to integrate the two above-said information systems by means of
prototyping method. So that the customers, employees and
business partners can reach the information flow just like
through one information system only. This research also
includes a case study on a large-scale enterpriserelated to the
problems and requirements of its information system integration,
and its integration strategy. Eventually, by applying the WBSIM
and underthe blueprint of the information environment of the
case, an initial prototype on integration, the Perfect
Information System (PIS), was designed so as to evaluate the
feasibility and effectiveness of WBSIM.
