scalable design-as the application grows, so too can the various components without affecting the underlying application logic 隨著應(yīng)用程序的增長,各種組件也能夠增長,同時不影響底層的應(yīng)用程序邏輯。
this allows for a scalable design in that new user-agent mappings can be added to the portal as new devices become available, but portlets need not change their behavior 這樣就可以使用可伸縮的設(shè)計了,在這種設(shè)計中,新的用戶代理映射可以作為新設(shè)備添加到門戶,但portlet不需要改變自己的行為。
