隨著信息技術和信息產業的不斷發展，軟件廣泛而深入地應用于各個領域。本文首先
分析目前軟件設計中三層體系結構的不足, 結合軟件開發工程實踐中對軟件體系結構的需
求，提出了一種基于UML 描述的軟件體系結構解決方案，將應用程序劃分為頁面表示層、業務外觀層、業務規則層、數據實體層、存儲過程層等五層，并定義了層間調用標準接口。

Abstract: As the development of information technology and information industry, the software is used in different areas in our life. It analyzes the shortage of the recent three layer structure first. Considering the demand of software design and development, the thesis has brought forward a kind software architecture solution based on UML description which divides application into page expression layer, business facade layer, business rule layer, data layer and stored procedure layer, cross-layer call standard interface dataset. This solution builds a special standard dataset on data exchanging among layers.
