運用RESTful Web Services 和 MVC 整合企業資訊系統之案例研究

Abstract

現今大型企業集團因產品與策略不同而建立或併購相關技術與行銷子公司、分公司或關係企業，這些集團公司內部資訊系統由於開發與導入的團隊不同造成不同公司系統與資料相互溝通複雜，此外同一間公司內部系統也因程式技術的與時俱進而有不同的開發方式與各式各樣方案導入，這樣造成系統維護困難與程式開發人員無法相互備份與協助，這樣不僅造成資訊人員斷層，各個系統之間功能與資料無法共用，如何有效整合不同系統，提升系統功能與資料共用與統一開發是大型企業的重要課題。 本論文針對一間大型電子公司進行資訊系統整合案例研究，針對公司內部四套系統進行整合研究，建立一個開發平台與規則。本次利用RESTful Web Services與 MVC設計系統框架，將畫面、流程、資料處理、服務這四大部分，分離設計與開發共用平台、定義統一規則，透過這樣的設計與共用開發，實驗證明達到整合系統服務、開發分工、共用程式讓舊程式碼行數減少91%、開發速度提升、跨平台。

Many large enterprise groups establish or merge with related technology and marketing companies, subsidiaries because of different production and strategies. Due to development and import by different IT working teams, the internal information programs and data of these groups are not easily communicated with each other. Moreover, various developing techniques and a wide range of projects implemented bring about the difficulties of system maintenance and back-up by program developers. As mentioned above, it causes the gap of IT technicians and non-shared of data and system functions. Thus, to integrate disparate systems effectively, to upgrade system performance, to share data and to unify development are important issues in many large group. This dissertation is a case study of information system integration for a large electronics company chosen as a main research target. It focuses on its internal four systems integration in order to reestablish a platform and rules. In the investigation, though RESTful Web Services and MVC, four main parts, view design, flow control, data process and services, are designed separately. And it makes a common platform and unifies rules clearly. Lastly, the finding proves the achievement of system and service integration, development division, decrease of past program code as 91%, obvious developing improvement and cross-platform.
