【正文】 摘 要 隨著社會(huì)發(fā)展的不斷進(jìn)步，民航事業(yè)的壯大，人們消費(fèi)水平的提高，乘坐民航的消費(fèi)者也越來越多，旅游也逐漸成為普通老百姓的生活組成部分，飛機(jī)票預(yù)定查詢系統(tǒng)在各機(jī)票預(yù)定網(wǎng)點(diǎn)中的作用也越顯重要。目前，我國一些旅行社和酒店的機(jī)票預(yù)定還停留在人工處理階段，這已經(jīng)嚴(yán)重制約了工作效率，在計(jì)算機(jī)技術(shù)高速發(fā)展的今天，有必要引入高效的計(jì)算機(jī)系統(tǒng)，來協(xié)助處理機(jī)票預(yù)定工作。 現(xiàn)設(shè)計(jì)一個(gè)機(jī)票預(yù)定管理系統(tǒng)的數(shù)據(jù)庫，首先根據(jù)問題需求設(shè)計(jì) ER 模型 ，然后再根據(jù) ER 模型設(shè)計(jì)出相應(yīng)的關(guān)系模型，對(duì)于每個(gè)關(guān)系模型的沒一個(gè)關(guān)系，可以設(shè)計(jì)出相應(yīng)的表格，接著分配表空間、創(chuàng)建視圖、設(shè)計(jì)存儲(chǔ)過程等等 關(guān)鍵詞： 機(jī)票預(yù)定管理系統(tǒng) 數(shù)據(jù)庫 ER模型 II Abstract With the continuous advancement of social development, the growth of civil aviation, the people consumption level enhancement, by civil consumers are more and more, tourism has gradually bee ordinary people39。s travel agencies and hotels booking the tickets still stay in manual processing stage, this has seriously restricted the work efficiency, in puter technology high speed development today, it is necessary to introduce efficient puter system, to assist in dealing with ticket reservation work. Therefore, development of a plete storage, query, print the ticket checking, function of realtime ticket reservation system be imperative. The design of a flight reservation management system database, according to the problem needs to design ER model, and then based on the ER model and design the corresponding relation model, for each relation model is not a relation, can design the corresponding form, then the allocation table space, create view, the design of the storage process.
