The back - end applications " trust " the front - end applications to send them only valid requests 后端應用程序“信任”前端應用程序發(fā)送給它們的都是有效的請求。
Each front - end application uses the stored credentials to access the back - end systems on behalf of all the users 每個前端應用程序使用存儲的憑證代表用戶訪問后端系統(tǒng)。
A " client " is a front - end application that uses the services provided by a server such as the sql server database engine “客戶端”是前端應用程序,它使用服務器(如sql server數(shù)據(jù)庫引擎)提供的服務。
The system attempts to protect against untrusted or malicious front - end applications by ensuring that each trusted front - end application is properly authenticated through the security manager 系統(tǒng)試圖通過保證每一個受信任的前端應用程序都是正確驗證過的(通過安全管理器) ,防止不受信任的或者惡意的前端應用程序。
Each front - end application is responsible for validating what a particular user is allowed to do through access control provided by the security manager , then forwarding appropriate requests on the user s behalf to the back - end 每個前端應用程序負責(通過由安全管理器提供的訪問控制)驗證某個用戶允許何種操作,然后代表用戶將相應的請求發(fā)給后端。
However , due to the lack of a systematic , scientific , convenient and practical applied model in the application to commodity residential quarters , the front - end application of architectural scheme has not been popularized in due time 但建筑策劃在商品住宅小區(qū)的應用由于缺乏系統(tǒng)的、科學的、方便實用的應用模式,導致建筑策劃在商品住宅設計前期的應用遲遲得不到推廣。
A design principle that focuses on clearly defined interfaces according to business rules and that best supports diverging it environments of different service agents , will be adopted to facilitate service agents to develop front - end applications and connect them to the back - end systems in government . furthermore , 這種設計的優(yōu)點在于采用了按業(yè)務規(guī)則明確界定的界面,并對不同服務提供者所采用的各類資訊科技系統(tǒng)具高度兼容性,方便服務提供者開發(fā)前端應用系統(tǒng),以及把這些系統(tǒng)與政府的后端系統(tǒng)連接。
