數(shù)據(jù)庫(kù)畢業(yè)設(shè)計(jì)---外文翻譯-其他專業(yè)(完整版)
【正文】 enders。 本章考慮了數(shù)據(jù)源的范圍能夠支持信用卡計(jì)劃的發(fā)展和可以應(yīng)用在市從各種需求種類中最大化申請(qǐng)數(shù)的工具。主要的國(guó)際信息局將提供能夠?qū)⒏黝悢?shù)據(jù)提供有意義的期望表 以等級(jí)的順序段系統(tǒng)。 總之最典型的從信息局得到的服務(wù)將按如下程序： 1． 收集整合所有的數(shù)據(jù)，包括將被篩選掉的 2． 合并不同的數(shù)據(jù)流 3． 根據(jù)市場(chǎng)和信用類別整理和分類數(shù)據(jù) 4． 利用預(yù)定的市場(chǎng)和信用 標(biāo)準(zhǔn)篩選數(shù)據(jù) 5． 整合和輸出改善的目錄 信息局將為使用他們的專門技術(shù)和系統(tǒng)而收取費(fèi)用，因此，應(yīng)該考慮到要處理的數(shù)據(jù)量和每個(gè)步驟所需的花費(fèi)，在較早期階段建設(shè)理想數(shù)據(jù)庫(kù)最花費(fèi)的步驟只在于低成本的篩選過(guò)程。 正如飛機(jī)訂票系統(tǒng)一樣，我希望出納員和顧 客通過(guò) ATM（自動(dòng)出納機(jī)）能同時(shí)查詢、更新銀行的數(shù)據(jù)。 客戶程序 服 務(wù)程序體系結(jié)構(gòu) 許多種現(xiàn)代軟件采用與客戶程序 服務(wù)程序體系結(jié)構(gòu)，這種體系結(jié)構(gòu)中，把一個(gè)進(jìn)程（客戶程序）發(fā)出的請(qǐng)求送到另一個(gè)程序去執(zhí)行。 。 在最簡(jiǎn)單的客戶程序 /服務(wù)程序體系結(jié)構(gòu)中，除了與用戶互相配合并將查詢或其他命令傳給服務(wù)程序的查詢接口以外，整個(gè) DBMS 就是一個(gè)服務(wù)程序。錯(cuò)誤是不能容忍的。 實(shí)現(xiàn)規(guī)定可提供的服務(wù)的范圍和水平是不可能的，但參考一下當(dāng)?shù)刂饕畔⒕謱?huì)是一個(gè)好的起點(diǎn)。通過(guò)選擇性的從帶好意的市場(chǎng)源購(gòu)買數(shù)據(jù)，然后通過(guò)覆蓋一般的事實(shí)推斷自分析常規(guī)經(jīng)過(guò)系統(tǒng)的廣泛的大量的工業(yè)信息，最好的國(guó)際的操作員現(xiàn)能提供市場(chǎng)和信用信息以支持新加入的重要新申請(qǐng)人的質(zhì)量。還有從姓名地址名單中精選出的數(shù)據(jù)，調(diào)查結(jié)果，以及其他市場(chǎng)分析數(shù)據(jù)，如：通過(guò)人口統(tǒng)計(jì)信息系統(tǒng) 這些數(shù)據(jù)的可用信和質(zhì)量會(huì)隨著國(guó)家地區(qū)的變化而變化，可用性不僅僅在某種程度由負(fù)責(zé)的代理商接受控制，而且有處理數(shù)據(jù)的可行性決定。 2. merge the various streams。 and 4 mercially piled data including and culled from name and address lists, survey results and other market analysis data, . neighborhoods and lifestyle categorization through geodemographic information systems. The availability and quality of this data will vary from country to country and bureau to bureau. Availability is not only governed by the extent to which the responsible agency has undertaken to record it, but also by the feasibility of accessing the data and the extent (if any) to which local consumer legislation or other considerations (. religious principles) will allow it to be used. Other limitations on the use of available data may lie in the simple impossibility or expense of accessing the information sources, perhaps because necessary consumer consent for divulgence has been withheld or because the records are not yet stored electronically. 學(xué)士畢業(yè)論文 2 The local credit information bureaux will be able to provide guidance on all of these matters, as will many local trade or professional associations or the relevant government departments. Data segmentation and Analyses The following remarks deal with the ways in which lawfully obtained data may then be processed and analyzed in order to maximize its value as the basis of a marketing prospect list. Examples of the types and uses of data that will play a role in the credit decision area are discussed later in the chapter, within the context of application processing. The key categories into which prospects may be segmented include lifestyle, propens
