系統(tǒng)分析與設(shè)計(jì)方法

前言

20世紀(jì)末，以計(jì)算機(jī)和通信技術(shù)為代表的信息科學(xué)和技術(shù)，對(duì)世界的經(jīng)濟(jì)、軍事、科技、教育、文化、衛(wèi)生等方面的發(fā)展產(chǎn)生了深刻的影響，由此而興起的信息產(chǎn)業(yè)已經(jīng)成為世界經(jīng)濟(jì)發(fā)展的支柱。進(jìn)入21世紀(jì)，各國(guó)為了加快本國(guó)的信息產(chǎn)業(yè)，加大了資金投入和政策扶持。為了加快我國(guó)信息產(chǎn)業(yè)的進(jìn)程，在我國(guó)《國(guó)民經(jīng)濟(jì)和社會(huì)發(fā)展第十個(gè)五年計(jì)劃綱要》中，明確提出“以信息化帶動(dòng)工業(yè)化，發(fā)揮后發(fā)優(yōu)勢(shì)，實(shí)現(xiàn)社會(huì)生產(chǎn)力的跨越式發(fā)展?！毙畔a(chǎn)業(yè)的國(guó)際競(jìng)爭(zhēng)將日趨激烈。在我國(guó)加入WTO后，我國(guó)信息產(chǎn)業(yè)將面臨國(guó)外競(jìng)爭(zhēng)對(duì)手的嚴(yán)峻挑戰(zhàn)。競(jìng)爭(zhēng)成敗最終將取決于信息科學(xué)和技術(shù)人才的多少與優(yōu)劣。在20世紀(jì)末，我國(guó)信息產(chǎn)業(yè)雖然得到迅猛發(fā)展，但與國(guó)際先進(jìn)國(guó)家相比，差距還很大。為了趕上并超過國(guó)際先進(jìn)水平，我國(guó)必須加快信息技術(shù)人才的培養(yǎng)，特別要培養(yǎng)一大批具有國(guó)際競(jìng)爭(zhēng)能力的高水平的信息技術(shù)人才，促進(jìn)我國(guó)信息產(chǎn)業(yè)和國(guó)家信息化水平的全面提高。為此，教育部高等教育司根據(jù)教育部呂福源副部長(zhǎng)的意見，在長(zhǎng)期重視推動(dòng)高等學(xué)校信息科學(xué)和技術(shù)的教學(xué)的基礎(chǔ)上，將實(shí)施超前發(fā)展戰(zhàn)略，采取一些重要舉措，加快推動(dòng)高等學(xué)校的信息科學(xué)和技術(shù)等相關(guān)專業(yè)的教學(xué)工作。在大力宣傳、推薦我國(guó)專家編著的面向21世紀(jì)和“九五”重點(diǎn)的信息科學(xué)和技術(shù)課程教材的基礎(chǔ)上，在有條件的高等學(xué)校的某些信息科學(xué)和技術(shù)課程中推動(dòng)使用國(guó)外優(yōu)秀教材的影印版進(jìn)行英語或雙語教學(xué)，以縮短我國(guó)在計(jì)算機(jī)教學(xué)上與國(guó)際先進(jìn)水平的差距，同時(shí)也有助于強(qiáng)化我國(guó)大學(xué)生的英語水平。為了達(dá)到上述目的，在分析一些出版社已影印相關(guān)教材，一些學(xué)校已試用影印教材進(jìn)行教學(xué)的基礎(chǔ)上，教育部高等教育司組織并委托高等教育出版社開展國(guó)外優(yōu)秀信息科學(xué)和技術(shù)優(yōu)秀教材及其教學(xué)輔助材料的弓l進(jìn)研究與影印出版的試點(diǎn)工作。為推動(dòng)用影印版教材進(jìn)行教學(xué)創(chuàng)造條件。

內(nèi)容概要

本書為教育部高等教育司推薦，國(guó)外優(yōu)秀信息科學(xué)與技術(shù)系列教學(xué)用書。 　　本次引進(jìn)的系列教材的影印出版工作，是在對(duì)我國(guó)高校的信息科學(xué)和技術(shù)專業(yè)的課程與美國(guó)高校的進(jìn)行對(duì)比分析的基礎(chǔ)上展開的；所影印出版的教材均由我國(guó)主要高校的信息科學(xué)和技術(shù)專家組成的專家組，從國(guó)外近兩年出版的大量最新教材中精心篩選評(píng)審?fù)ㄟ^的內(nèi)容新、有影響的優(yōu)秀教材；影印教材的定價(jià)原則上應(yīng)與我國(guó)大學(xué)教材價(jià)格相當(dāng)。 　　本書適合作為高等院校信息系統(tǒng)或商業(yè)類專業(yè)本科或研究生教材，亦適合于作為系統(tǒng)開發(fā)人員的參考書。

章節(jié)摘錄

插圖：The system designer’S view of data consists of data structures，database schemas，fields，indexes，and other technology-dependent components.Most of these technical specifications are tOO complex tO be reasonably understood by system users.The systems analyst and／or database specialist design and document these technical views of the data.As shown in Figure 2.4.the system designers’view of data is a database schema.A database schema iS the transformation of the data requirements（system users'view）into a set of data structures that can be imple  mented using the chosen DBMS.Once again，this book will teach tools and techniques for transforming user data requirements into database schemas.System Builders View of DATA The final view of data is relevant to the system builders.In the DATA column of Figure 2.4，system builders are closest to the actual database lnanagetnent systenl（DBMS）technology.They must represent data in very precise and unforgiving languages.The most commonly encountered data base language is SQt（Structured Query Language）.Alternatively，many database management systems，such as Access and FoxPro,include proprietary languages or facilities for constructing a new database.Not all information systems use database technology to store their business data.Older legacy systerns were built with flat-file technologies such as VSAM.These flat-file data structures were constructed direcfly within the programming language used to write the programs that use those files.For example.in a COBOL pro gram the flat-file data structures are expressed as PICTURE clauses in a DATA DIVI SION.This book will not teach either database or flat-file constmction languages，only place them in the context of the DATA building block of information systems.
