Explores the design issue of functional decomposition and how session ejbs can be used to solve this problem 研究了功能分解的設(shè)計(jì)問題及如何使用會話ejb解決這個問題。
The rule of thumb to remember is that service oriented architectures require functional decomposition : decomposition results in components that ultimately need to be managed , and components in java are best implemented with session ejbs with or without a helper class , which makes the session ejb a facade 憑經(jīng)驗(yàn)來看,面向服務(wù)的體系架構(gòu)需要功能分解:分解導(dǎo)致組件最終需要進(jìn)行管理,使用會話ejb最佳的實(shí)現(xiàn)java中的組件(使用或不使用幫助類,該類使會話ejb成為外觀) 。
In the first part of this paper , a three - level situation assessment functional model , which consists of situation perception , situation recognition and situation projection , is presented and it leads us to a functional decomposition of a multilevel situation assessment process . the essential characteristics and reasoning mode of situation assessment are analyzed in detail with some examples present and the common essence of situation assessment and its reasoning frame is concluded . after discussion of algorithms of situation assessment , a universal template matching algorithm is brought forwards 本文首先提出態(tài)勢覺察、態(tài)勢理解及未來態(tài)勢預(yù)測三級態(tài)勢估計(jì)功能模型,然后具體分析了各個部分實(shí)現(xiàn)的功能;通過幾個實(shí)例分析了態(tài)勢估計(jì)問題的本質(zhì)特征和推理模式,歸納出態(tài)勢估計(jì)及其推理框架的共性;對態(tài)勢估計(jì)推理算法做了一些研究,提出一個通用的態(tài)勢估計(jì)模板匹配算法。

Functional decomposition refers broadly to the process of resolving a functional relationship into its constituent parts in such a way that the original function can be reconstructed (i.e.
