电子词典的设计与实现摘要二十世纪后半叶，伴随着社会的迅速发展与进步，以电子计算机为代表的现代科学获得了突飞猛进的发展并迅速和人们的日常生活结合在一起。计算机技术的发展和进步也使电子语言词典的诞生成为可能。虽然只有十来年的历史，电子词典却已经迅速发展壮大，成为词典家族中具有旺盛生命力的一员。尽管目前它尚不足以取代传统词典，但在英语学习和教学中，由于它实用、快捷、准确、经济等特点，已经成为传统英汉词典的有力竞争者，并对传统的词典提出了挑战。本文将要介绍的软件就是一个多功能学单词软件，主要介绍了这个软件制作环境，制作流程，对数据库的操作以及它的使用方法。用户可以根据自己的需要去查询单词，添加单词，删除单词，编辑单词,浏览词库中的单词，也可以进行四六级考研词汇等。另外，它还给单词学习者们提供了一个背单词的好方法。每一个用户都可以通过创建一个用户名来背诵单词，随时查看自己的历史记录，以便确定自己的背诵进度。本文从软件工程的角度进行了详细的阐述。该系统的开发工具是MicrosoftVisualBasic6.0，使用的数据库为MicrosoftAccessversion7.0。关键词：电子词典，MicrosoftVisualBasic6.0，数据库ABSTRACT20halfaftercenturiesleaf,withtherapiddevelopmentofsociety,withcomputerforrepresentativeofthedevelopmentthatmodernscienceacquirestoadvancebyleapsandboundscombinequickcombinetogetherwiththepeople'sdailylife.ThecalculatortechnicaldevelopmentandprogressesalsomakethenaissanceoftheelectronicslanguageElectronDictionarymakepossible.Althoughonlytenhistoriesofthenextyears,theelectronicsElectronDictionaryhasalreadydeveloppedquicklystrong,becomehavingamemberoftheprosperousvitalityintheElectronDictionaryhousehold.ThoughitisstillnotenoughtoreplacethetraditionalElectronDictionarycurrently,inEnglishstudyandteaching,becauseofitpractical,fast,accurate,economyetc.characteristics,havealreadybecometheemollientcompetitorofthetraditionalEnglish-to-ChineseElectronDictionary,andputforwardthechallengetothetraditionalElectronDictionary.Thesoftwarethatthistextwillintroduceisamulti-functionlearnthesinglephrasesoftware,mainlyintroducedthissoftwaremanufactureenvironment,themanufactureprocess,tooperationanditsoperationmethodsofthedatabase.Thecustomercansearchthesinglephraseaccordingtoowndemand,increasingthesinglephrase,deletingthesinglephrase,edittingsinglephraseetc..Moreover,itreturnedtoprovideagoodmethodthatcarriesonthebackthesinglephraseforthesinglephraselearners.Eachcustomercanpasstoestablishanuser'snametorecitefrommemorythesinglephrase.Atanytimelookintoownhistoryrecord,forthepurposeofassurancerecitefrommemorythedegreeofprogressownly.Carriedontoelaboratecarefullyfromtheangleofthesoftwareengineering.ItisAccessdatabasethatthedevelopmenttoolofthatsystemisthepowerbuilder9.0databasesoftheusages.Keywords:TheElectronDictionary,MicrosoftVisualBasic6.0,Accessdatabase目录摘要.................................................1ABSTRACT.................................................21概述................................................12系统分析..............................................22.1系统目标...................................................22.2系统需求分析...............................................22.2.1功能需求.............................................22.2.2性能需求.............................................33系统开发工具简介..............................................................................43.1VisualBasic6.0概述.....................................43.1.1VisualBasic6.0简介................................43.1.2...
