《C#程序設(shè)計(jì)》課程設(shè)計(jì)公交路線(xiàn)查詢(xún)

1、太湖學(xué)院c#程序設(shè)計(jì)課程設(shè)計(jì)題目：公交路線(xiàn)查詢(xún)機(jī) 電學(xué)院計(jì)算機(jī)科學(xué)與技術(shù)專(zhuān)業(yè)學(xué) 號(hào)：學(xué)生姓名：班 級(jí)：計(jì)科84成 績(jī)：2012年 1月 需求分析：隨著現(xiàn)代社會(huì)的發(fā)展，交通也越來(lái)越發(fā)達(dá)，人們也開(kāi)始不斷的外出旅游，不管是市內(nèi)還是市外對(duì)一個(gè)準(zhǔn)確明了的交通路線(xiàn)需求越來(lái)越大，以前我們只能通過(guò)電話(huà)咨詢(xún)、看地圖、向路人打聽(tīng)來(lái)了解訊息，這不僅浪費(fèi)精力財(cái)力時(shí)間，而且極為不方便。在這樣一個(gè)需求下，我們所設(shè)計(jì)的公交路線(xiàn)查詢(xún)系統(tǒng)就產(chǎn)生了很大的價(jià)值，它能很方便的查詢(xún)到公交路線(xiàn)，準(zhǔn)確的告訴你從a到b該怎么去才最為快捷！這也是我們?cè)O(shè)計(jì)這個(gè)系統(tǒng)的初衷！1.功能需求首先我們系統(tǒng)最基本要滿(mǎn)足顧客的需求就是公交路線(xiàn)的查詢(xún)。但是我們

2、清楚的知道，死的列表將造成許多不便，因?yàn)槁肪€(xiàn)會(huì)隨著城市建設(shè)而變化，所以我們的路線(xiàn)是可以實(shí)時(shí)的去更新的，這樣就牽扯到再數(shù)據(jù)庫(kù)中的更新、刪除功能，附帶通過(guò)報(bào)表清楚的顯示出來(lái)修改后的內(nèi)容。觸發(fā)器功能實(shí)現(xiàn)公交路線(xiàn)中的一些數(shù)值計(jì)算，比如幾站路等。我們所要實(shí)現(xiàn)的就是站點(diǎn)查詢(xún)、換車(chē)查詢(xún)、線(xiàn)路查詢(xún)。2.數(shù)據(jù)需求數(shù)據(jù)庫(kù)中包含管理者的賬戶(hù)密碼。公交路線(xiàn)數(shù)據(jù)（包括起始站到終點(diǎn)站的其間所有站點(diǎn)）。3.性能需求客戶(hù)需要的是一個(gè)快捷準(zhǔn)確的查詢(xún)系統(tǒng)，包括一次轉(zhuǎn)車(chē)到達(dá)以及二次轉(zhuǎn)車(chē)到達(dá)，不能有任何差錯(cuò)。所以關(guān)于線(xiàn)路查詢(xún)的c#程序語(yǔ)句要考慮周全不能有任何差池。數(shù)據(jù)庫(kù)中數(shù)據(jù)也需要其準(zhǔn)確性。概要設(shè)計(jì)：設(shè)計(jì)思想： 隨著公路規(guī)模的不斷擴(kuò)

3、大，公交數(shù)量的急劇增加，有關(guān)公交管理的各種信息量也在不斷成倍增長(zhǎng)。面對(duì)龐大的信息量，就需要有公交信息管理系統(tǒng)來(lái)提公交房管理工作的效率。通過(guò)這樣的系統(tǒng)，我們可以做到信息的規(guī)范管理和快速查詢(xún)，從而減少了管理方面的工作量。目前，我國(guó)各省市的公交查詢(xún)工作還未實(shí)現(xiàn)數(shù)字化。整個(gè)過(guò)程既浪費(fèi)能源又浪費(fèi)資源。最后導(dǎo)致浪費(fèi)時(shí)間，無(wú)法按時(shí)到達(dá)目的地。因此，開(kāi)發(fā)一個(gè)能夠?qū)ψ钚碌墓痪€(xiàn)路進(jìn)行查詢(xún)的信息平臺(tái)就顯得尤其重要。所開(kāi)發(fā)的系統(tǒng)將在一定程度上能夠克服以上的種種缺點(diǎn)，實(shí)現(xiàn)各項(xiàng)工作在線(xiàn)完成，為乘客提供一個(gè)完全公開(kāi)、開(kāi)放、完善的管理平臺(tái)，放便了乘客的出行，大大節(jié)省了乘客的寶貴時(shí)間。通過(guò)這樣的系統(tǒng)，我們可以做到信息的規(guī)范管

4、理和快速查詢(xún)，實(shí)現(xiàn)了公交信息管理的系統(tǒng)化、規(guī)范化和自動(dòng)化，這樣不僅減少了管理工作量，還提高了查詢(xún)效率，降低了查詢(xún)成本。實(shí)現(xiàn)模塊：1. 選擇模塊：using system;using system.collections.generic;using system.componentmodel;using system.data;using system.drawing;using system.text;using system.windows.forms;namespace bus public partial class form3 : form public form3() initial
