1、价了、厂之摘要本文设计并实现了茶叶销售管理信息系统(简称TSMIS)。TSMIS是一个自动信息系统,服务商可以使用该系统高效地管理定单及茶叶销售信息,而客户可以在线定制购单。系统是使用多层次体系结构设计并实现的。我们以一个典型的茶叶销售公司—茶叶贸易公司2、用性、层次易修改性、多种语言支持、集中式组件、更有效的数据访问以及可维护性。本项目中,TSMIS由数据层、中间层和表示层组成。数据层处理数据库及其它组件如存储过程。后台数据库使用SQLServer2000设计。而中间层则与COM组件打交道,用来完成不同的商业规则。表示层则涉及到了用户接口。用户接口由前台和基于We],的应用组成,由此访问COM组件。我们选择VisualBasic实现COM组件和前台应用;而ASP,HTML,JavaScript,andVBScript用来实现基于Web的应用。后者的使用对象主要是在线的或潜3、在的在线用户。我们通过模拟潜在的用户,测试了TSMIS并且测试成功。关键字:在线漓线定单,茶叶销售信息,多层次,数据层,中间层,COM组件,ADO,前台应用,基于Web的应用。ABSTRACTThisprojectisabouttheTeaSalesManagementInformationSystem(TSMIS),especiallyitsdesignandimplementation.TSMISisanautomatedinformationsystemthatallowsthebusinessownertoeff4、icientlymanageordersandteasalesinformationItalsoallowscustomerstomakeonlineorders.Thesystemisdesignedandimplementedusingmulti-tierarchitecture.Tofindoutsomeinformationneeds,acasestudyofatypicalteasellercompanynamedTeaTradeCompany(TIC)wasconsidered.Themulti-tierar5、chitectureseparatesapplicationfunctional仰intoindependentlayersortiers.Thatis,multitiermodeladds1哈callayer(s)inthemiddle-tierofthetraditionaltwo-tierarchitecture.Thisovercomesthemultiplelimitationsofthetwo-tiermodel.Atypicalmulti-tierapplicationconsistsofthreeelem6、entsnamelythepresentation-tier,middle-tier(applicationlogic),andthedata-tier.Themulti-tierarchitectureprovidessomeadvantages.Theyincludethereusability,easiermodificationoflayers,multi-languagesupport,centralizedcomponents,moreefficientdataaccess,andmaintainabilit7、y.Inthisproject,theTSMISiscomprisedofthedata-tier,而ddle-tier,andpresentation-tier.Thedata-tierdealswiththedatabaseandothercomponentssuchasstoredproceduresSQLServer2000wasusedasaback-enddatabaseserver.Themiddle-tier,inturn,dealswiththeCOMcomponent,whichimplementth8、ediferentbusinessrules.Asforthepresentation-tier,itconcernstheuserinterface.Userinterfaceismadeupofthefrontdeskandtheweb-basedapplications,whichaccesstheCOMcom
