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(wèn)題及如何使用會(huì)話ejb解決這個(gè)問(wèn)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(lái)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(huì)話ejb最佳的實(shí)現(xiàn)java中的組件(使用或不使用幫助類(lèi),該類(lèi)使會(huì)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(shì)覺(jué)察、態(tài)勢(shì)理解及未來(lái)態(tài)勢(shì)預(yù)測(cè)三級(jí)態(tài)勢(shì)估計(jì)功能模型,然后具體分析了各個(gè)部分實(shí)現(xiàn)的功能;通過(guò)幾個(gè)實(shí)例分析了態(tài)勢(shì)估計(jì)問(wèn)題的本質(zhì)特征和推理模式,歸納出態(tài)勢(shì)估計(jì)及其推理框架的共性;對(duì)態(tài)勢(shì)估計(jì)推理算法做了一些研究,提出一個(gè)通用的態(tài)勢(shì)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.
