資料元件再利用架構

Abstract

今日，軟體發展的困難度與日俱增。隨著系統的成長，軟體複雜度越來越高，發展的速度因之減緩。軟體再用可以加快軟體發展和增進效率。為了解決這個問題，已有許多的方法被提出來。UML (Unified Modeling Language)就是最常使用的方法之一，利用了物件導向分析與設計的技術，建立起系統的模型。雖然UML可以處理大多數的系統，但對於關聯式資料庫中的無法建立適當的模型。 在本論文中，我們提出了一個提昇資料元件使用率的架構。我們將把關聯式資料庫中的資料，帶入系統分析與設計這個階段，讓這些資料元件被包裝成MTS(Microsoft Transaction Server)元件。同時，我們也在系統設計與執行的階段，提供異動(Transaction)的機制。如此一來，資料元件可以更容易的發展與使用，以達成提昇軟體開發效能與品質的目的。

It is increasingly hard to develop a system. As the system growing, the more complex the system is, the slower software develops. Software reuse can make software developing fast and efficiently. Many methodologies are purposed for the objective. The UML (Unified Modeling Language) is one of them and used popularly. It can model a system and design the detail by OOA (Object-Oriented Analysis) and OOD (Object-Oriented Design). It can process the general system well but unfortunately, the RDBMSs (Relation DataBase Management Systems) data cannot be modeled by it. In this thesis, we propose a framework to leverage the utilization of RDBMSs data. We bring RDBMSs data into the stage of system analysis and design. The data are packaged as MTS (Microsoft Transaction Server) component that can be manipulated easily. We also provide transaction mechanism in the system in both design and run-time stage. In short, the data-aware component can be easy to develop to fulfill the goal of promoting the quality and efficiency of developing software.
