傳統的物件導向設計已發展出許多成熟的設計樣式(Design Pattern)用來解決軟體設計上的問題，服務導向架構(Service-Oriented Architecture，SOA) 在近年來不斷的被討論，服務導向架構的設計樣式逐漸在發展中。本論文以物件導向設計樣式為基礎，發展一服務導向設計樣式－財務金融指標評估(Financial Evaluation) Façade，應用於財務金融領域，進行財務金融指標的評估。可依不同的財務金融指標評估需求對財務金融指標評估Façade實作，以達到系統目的。 / There are many mature design patterns already developed with traditional Object-Oriented Design for resolving problems of software design. Service-Oriented Architecture (SOA) is discussed constantly in the recent years, and Service-Oriented design patterns are developed gradually. In this paper, we develop a Service-Oriented design pattern － Financial Index Evaluation Façade which based on Object-Oriented design patterns. It is a domain-specific design pattern applied to financial index evaluation. For different situation, we can implement Financial Index Evaluation Façade for request to achieve system objective.
