Next , we installed and configured the ibm http server that comprises the user presentation tier 接著,我們安裝和配置ibm http server ,它構(gòu)成用戶表示層。
These components , or javabeans , then perform back - end business processing on behalf of the presentation tier 這些組件或者javabean再代表表示層執(zhí)行后端業(yè)務處理。
I ll introduce the framework at the presentation tier to handle sanity checks on static data sent by the browser 我將在表示層引入這個框架,負責對由瀏覽器發(fā)送的靜態(tài)數(shù)據(jù)進行安全檢查。
By keeping data in a dataset , you can easily move it between the presentation tier , business tier , and data tier of your applications 通過在數(shù)據(jù)集內(nèi)保存數(shù)據(jù),您可以方便地將它在應用程序的表示層、業(yè)務層和數(shù)據(jù)層之間移動。
It is designed as a midplet of j2me application . in presentation tier , we choose struts , servlet and jsp as the major implementations 在表示層,我們選用了struts的mvc框架及標準的servlet 、 jsp等技術(shù),實現(xiàn)了命令模式、業(yè)務代理模式等。
In system analysis process , we divide mbp into five logical tiers . they are client tier , presentation tier , business tier , data access tier and eis tier 在開發(fā)的分析階段,我們將系統(tǒng)在邏輯上分成五層,它們分別是客戶層、表示層、業(yè)務邏輯層、數(shù)據(jù)訪問層和eis層。
In presentation tier , we provide four corresponding components for four clients . business tier is to provide business service for the presentation tier , and all the business logic are implemented in this tier 系統(tǒng)的業(yè)務邏輯層主要是為四種表示層組件提供業(yè)務邏輯服務,當表示層需要業(yè)務邏輯相關(guān)的操作時,都是通過調(diào)用業(yè)務邏輯層的服務來實現(xiàn)的。
This thesis presents the realization of the web system on the thought of 3 - tier architecture : data , middle and presentation tiers . it concludes the database design , the way of programming object oriented components , the access of database , the web form design based on asp . net and the authorization control . at last , it gives the requirement of running this system and the way of security management 在系統(tǒng)實現(xiàn)上,根據(jù)web三層設計的思想,從數(shù)據(jù)層、中間層和表現(xiàn)層來設計系統(tǒng),其內(nèi)容包括數(shù)據(jù)庫的設計,面向?qū)ο蟮慕M件編程, web數(shù)據(jù)庫訪問技術(shù)的研究,基于asp . net的web表單的設計,權(quán)限控制設計等,并對系統(tǒng)安全管理的問題進行了探討和研究。
In this project , the actual three - tier architecture was realized and the business logic was packed into ejb components , which acted as an agent between presentation tier and resource tier ; the separation between business logic and system service was realized , which enabled developers to devote their mind to the realization of business logic and improved the software quality and efficiency ; the stretchable enterprise application was realized through tier - dispatched pattern , which has relax coupling relationship between tiers and each tier has its own role and the methods inside the tier will be changed without affection to the call - up relationship between tiers 主要成果是: ( 1 )實現(xiàn)了真正意義上的三層體系結(jié)構(gòu),將業(yè)務邏輯封裝在ejb組件中, ejb組件作為表現(xiàn)層的代理對數(shù)據(jù)層進行數(shù)據(jù)操作; ( 2 )使用ejb技術(shù),實現(xiàn)了業(yè)務邏輯和系統(tǒng)服務之間的分離,使得開發(fā)人員可以專注于業(yè)務邏輯的開發(fā),從而提高軟件的質(zhì)量和開發(fā)效率; ( 3 )通過分層模式,實現(xiàn)了可伸縮的企業(yè)應用程序。層與層之間松散耦合,每個層針對特定的角色,每一層內(nèi)部實現(xiàn)方法的變化不影響層與層之間的調(diào)用關(guān)系,可以更好地適應客戶需求的變化。
With a reference to windows dna ( windows distributed internet application architecture ) , the platform is separated into several reasonable tiers . the presentation tier is designed to communicate with clients , application logic tier is designed to deal with simulation algorithms , and the data tier is designed to store the simulation data 在參考了windowsdna ( windowsdistributedinternetapplicationarchitecture , windows分布式internet應用程序體系結(jié)構(gòu))的基礎(chǔ)上,本論文對建立的分布式計算機仿真平臺進行了合理的層次劃分。
