Structured Web Programming

Abstract

資訊網應用程式的開發，往往需要整合許多的技術與工具。這些工具包括：HTML、SQL、電子郵件、程式語言等。因此，程式設計人員往往花費許多的時間整合許些工具，而不是把時間用在解決問題上。此外，這些不同工具的合併使用，常降低應用程式的可讀性，因此增加了程式維護的困難。本篇論文所介紹的OpenFlow資訊網應用程式開發平台，藉由將HTML的文件與程式碼分離的設計原則、使用者資料管理的自動化、及將資訊網應用程式依照其網頁展示的流程分成不同步驟的開發方式，解決了上述常見的資訊網應用程式開發的問題。應用OpenFlow來開發資訊網應用程式能夠將程式的結構以較高階的方式表達，也整合了分析設計與程式開發的步驟。Developing Web applications is mostly an unorganized task involving interactions with HTML, SQL, email, programming languages, and other tools or software. Developers spent most of their time integrating these languages or tools rather than solving the problem itself. Furthermore, using these different tools or languages in the same source file often makes improving the readability of the applications difficult. This paper presents the OpenFlow divides the task of HTML presentation and persistent data management, allows the structure of an application to be expressed at a higher level, and provides direct mapping between high-level design and low-level implementation of applications.
