python實(shí)現(xiàn)外賣(mài)信息管理系統(tǒng)

 更新時(shí)間：2018年01月11日 09:26:18   作者：雙安  
這篇文章主要為大家詳細(xì)介紹了python實(shí)現(xiàn)外賣(mài)信息管理系統(tǒng)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文為大家分享了python實(shí)現(xiàn)外賣(mài)信息管理系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

一、需求分析

需求分析包含如下：

1、問(wèn)題描述

以外賣(mài)信息系統(tǒng)管理員身份登陸該系統(tǒng)，實(shí)現(xiàn)對(duì)店鋪信息、派送員信息、客服人員信息、訂單信息、配送信息等進(jìn)行有條件查詢(xún)以及信息的錄入、修改、刪除等功能。

2、系統(tǒng)功能描述

（1）信息錄入：使用wxpython設(shè)計(jì)排版編寫(xiě)窗口界面，給出錄入信息的接口，通過(guò)python語(yǔ)句實(shí)現(xiàn)與數(shù)據(jù)庫(kù)的連接，從而向數(shù)據(jù)庫(kù)中插入相應(yīng)數(shù)據(jù)。

（2）信息修改：使用wxpython設(shè)計(jì)排版編寫(xiě)窗口界面，給出修改信息的接口，通過(guò)python語(yǔ)句實(shí)現(xiàn)與數(shù)據(jù)庫(kù)的連接，從而修改數(shù)據(jù)庫(kù)中相應(yīng)數(shù)據(jù)。

（3）信息查詢(xún)：在窗口界面中，通過(guò)響應(yīng)的按鈕觸發(fā)，實(shí)現(xiàn)與數(shù)據(jù)庫(kù)的連接查詢(xún)，得到所有在線(xiàn)店鋪信息。

（4）數(shù)據(jù)統(tǒng)計(jì)：在數(shù)據(jù)庫(kù)中編寫(xiě)相應(yīng)的存儲(chǔ)過(guò)程，輸入店鋪名稱(chēng)即可select其所管理的派送員和客服人員。

3、系統(tǒng)功能模塊圖

二、概念結(jié)構(gòu)設(shè)計(jì)

系統(tǒng)整體的E-R模型：

三、邏輯結(jié)構(gòu)設(shè)計(jì)

本系統(tǒng)所用到的表結(jié)構(gòu)以及其聯(lián)系：

1、店鋪基本信息foodshop表

 

主鍵：shop_name

2、客服基本信息server表

主鍵：server_id

外鍵：shopname_shop_name

參考表：shopname 參考屬性：shop_name

3、派送員基本信息courier表

 

主鍵：courier_id

外鍵：shopname_shop_name

參考表：shopname 參考屬性：shop_name

4、學(xué)生基本信息student表

 

主鍵：student_phone

5、訂單基本信息book表

 

主鍵：（student_phone，server_id）

外鍵：student_phone，參考表student，參考屬性student_phone

外鍵：server_id，參考表server，參考屬性server_id

6、配送基本信息delivery表

主鍵：（student_phone，courier_id）

外鍵：student_phone，參考表student，參考屬性student_phone

外鍵：courier_id，參考表courier，參考屬性courier_id

四、具體實(shí)現(xiàn)

登陸界面：

程序演示：

（1）店鋪信息

（2）店鋪上架

（3）店鋪下架

（4）派送員信息

（5）訂單信息

（6）買(mǎi)家訂餐

（7）修改訂單

查看訂單信息確認(rèn)已經(jīng)修改

 

至此python借助pymysql操作Mysql數(shù)據(jù)庫(kù)的增、刪、改、查功能演示完畢，剩下功能不一一截圖，原理類(lèi)似。

五、總結(jié)

通過(guò)本次課程設(shè)計(jì)，我對(duì)本學(xué)期所學(xué)的“數(shù)據(jù)庫(kù)”和python內(nèi)容有了更深一層的理解和學(xué)習(xí)。對(duì)數(shù)據(jù)庫(kù)的認(rèn)識(shí)不再僅僅停留在課本的理論知識(shí)上，能夠更加清楚的理解其后臺(tái)的操作流程。對(duì)python的應(yīng)用不再局限于編寫(xiě)簡(jiǎn)單小程序，而是做到了與數(shù)據(jù)庫(kù)進(jìn)行連接，通過(guò)wxpython前臺(tái)窗口，對(duì)數(shù)據(jù)庫(kù)傳入相應(yīng)的sql語(yǔ)句，從而實(shí)現(xiàn)數(shù)據(jù)庫(kù)的插入、修改、增加、刪除等操作，實(shí)現(xiàn)sql語(yǔ)句的前臺(tái)明了化。在設(shè)計(jì)E-R圖時(shí)，采用了Navicat for mysql這一針對(duì)mysql的可視化工具，使得表與表之間的關(guān)系得以清晰的呈現(xiàn)，這次課程設(shè)計(jì)使我獲益匪淺，在鞏固與拓展知識(shí)的同時(shí)，還學(xué)會(huì)了許多工具的使用，這對(duì)以后的開(kāi)發(fā)提供了寶貴的經(jīng)驗(yàn)和基石。

更多學(xué)習(xí)資料請(qǐng)關(guān)注專(zhuān)題《管理系統(tǒng)開(kāi)發(fā)》。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
