- This paper introduces a new platform - - - - j2ee , describing in detail its structure and main technologies , including servlet , jsp , ejb and a group of common apis ; it also studies on j2ee " s application in developing enterprise systems from two aspects ? - tier architecture & component - based development ; it also discusses j2ee " s evolution and future direction . the credit risk is an important part of the whole bank " s financial risk , and the credit risk mis is a new type of enterprise system
本文介紹了構造java企業(yè)級系統(tǒng)的最新平臺? ? j2ee ，詳細闡述了它的組成、基于j2ee構建企業(yè)系統(tǒng)常用的主要技術，包括servlet 、 jsp 、企業(yè)javabean和一組常用api ；研究了j2ee的在企業(yè)級系統(tǒng)開發(fā)中的應用，基于j2ee邏輯體系結構，從分布式多層結構和基于組件開發(fā)兩個方面闡述了對企業(yè)系統(tǒng)提供的強有力的支持，以及j2ee的發(fā)展和未來方向。 - Owing to its excellent adaptability to large angle - displacement between two transmission shafts and other characteristics such as large transmission ratio , terse mechanism , high transmission efficiency , cardan cross - pin spindles has been widely used as an important mechanical part in transport machines , metallurgy machines , petrolic machines , heavy machines , etc . as an effective and promising approach to resolve complicated development of modern software , component - based development ( cbd ) is put forward to change the present way of software development by producing software through assembling ready software components and its final target is to realize the industrialization of software development totally
十字軸式萬向聯(lián)軸器能夠很好地適應傳動軸間的較大角位移，而且具有傳遞扭矩范圍大、結構緊湊、傳動效率高、維修保養(yǎng)方便等特點，是一種重要的傳動部件，因此在交通運輸、冶金、重型機械等領域中得到廣泛應用?；诮M件的開發(fā)是近幾年發(fā)展并日益成熟起來的一種軟件開發(fā)新方法，其核心思想是以流水線方式、通過組裝組件生產(chǎn)軟件，從而容易實現(xiàn)軟件開發(fā)的工業(yè)化。 - Based on the main idea of " the map display of comgis " , the concept and technological foundation of comgis , the theory of component ( com ) , and component - based development ( cbd ) are discussed separately in this paper ; and some products of comgis in existence are studied . also , system designs and development models of the map display of comgis have been presented based on recent practices , including the structure of data and map symbol library
本文以“組件式地理信息系統(tǒng)的地圖顯示”為核心，分別闡述了組件、組件gis和組件式軟件開發(fā)的理論和方法，對現(xiàn)有組件gis產(chǎn)品進行了研究分析，重點設計實現(xiàn)了地圖顯示的組件，其中涉及到了數(shù)據(jù)結構的定義和地圖符號庫的建立，以及導航功能的設計實驗等內(nèi)容。 - Under the analysis of the deficiency of traditional b / s model and the tendency of enterprise computing development , this paper puts forward an intranet application system computing model based - on java and xml with the combination of the new software technology such as component - based development , java and xml
<中文摘要> =本文分析了傳統(tǒng)b / s模型的不足以及目前企業(yè)計算發(fā)展的趨勢，結合當前軟件界新出現(xiàn)的基于組件的開發(fā)、 java技術和xml等，提出了一種基于java和xml的intranet應用系統(tǒng)計算模型，并將其應用到了具體的工程實踐中。 - The core parts of com technologies is discussed , and it is also noted that the paper expatiates software technologies concerning components - based development which include components objects model ( com ) , distributed components object model ( dcom ) , objects linking and embedding ( ole ) , as well as activex , and analyzes the application of these technologies in gis
文中討論了com的核心部分，并闡述與組件式軟件技術相關的組件對象模型( com ) 、分布式組件對象模型( dcom ) 、對象連接與嵌入( ole )和activex等內(nèi)容，并分析了這些技術在gis中的應用。 - To develop the teaching evaluation system with component - based development methods not only use the existing resources fully , but also decrease the period in development . at present , the related researches mainly base on rich components , but there are also problems how to use the reusable components and make the architecture in some domains to fit the specified application
目前此方面的研究主要是在組件資源比較豐富的情況下進行的，但如果可重用組件較少，在開發(fā)過程中如何使用可重用組件，以及如何使領域內(nèi)的體系結構符合領域內(nèi)某一具體的應用，仍然是有待于進一步研究的問題。
