?隨著軟件規模和復雜程度不斷地擴大和增加，軟件開發已不再完全取決于數據結構和軟件算法的選擇，而是在很大程度上取決于軟件體系結構，軟件體系結構模型是影響軟件的關鍵。根據待開發軟件的應用場合和所處理問題的特點，選取合適的體系結構，有利于縮短開發周期、節約開發成本和軟件維護。經過對常見軟件體系結構模型的分析后，提出一種新的軟件建模方式——基于中間層的軟件體系結構。然后，通過一個實際的例子——校園一卡通系統，闡述了所提出的基于中間層的軟件體系結構模型。

Abstract:: ?With the enlargement of the softwares cope and the increase of the complicated level， the success of software development is not depended on the selection of data organization and software algorithm completely， but to great extent is depending on the software systems structure， the software system structural models become the key which influences software. A proper architectural approach leads to shoter software development life-cycles， resulting in savings in software development and maintenance cost. After analyzing several common software architectural styles， a new software modeling approach- architecture model based on the middle layer is presented. Then， through a practical example-the campus card system. It supports the new architecture model-middle-layer software architecture
