基於JSON 文件之共通資料交換介面系統之研究
以運用WSGI 框架實作之課程查詢系統為例

近年來，隨著網際網路與資訊產業的蓬勃發展，各式各樣的網頁系統與應用程式軟體不斷的推陳出新，這些系統與應用程式之間，事實上有許多是具有類似功能的，例如課程查詢系統，然而，因為是不同學校開發，其使用者介面各不相同，造成使用者的不便。本研究以此為實際的標的，嘗試制定一套JSON 文件，作為其課程資料交換之共通標準，並且實作了一個簡易的課程查詢系統作為測試。若未來各校均能採用此一資料交換之標準，則一方面可以讓使用者透過自己熟悉的操作介面查詢不同學校之課程，也能減輕各校的系統開發人員在開發使用者介面上的負擔，也更希望此一方式能廣泛運用到其他類似的資訊查詢系統上。

Recently, with the rapid development of internet and information industry, a wide range of web systems and applications software has been constantly innovated. among these web systems, there are many similar features, such as course search systems. However, it is difficult for users since the user interfaces are different because the systems are developed by different developers. In this study, we try to develop a suit of JSON documents as a common standard for data exchange between frontend programs and backend web servers. Suppose that every school can develop their course query web systems based on this standard in the future. Then the users can select one of their most favorite user interface for querying courses, and the loading of the system developers in schools can be reduced since they do not design the fronted user interface. We hope such a way can be applied to other similar information system.
