快递管理系统 [英] courier managment system

问题描述

我目前正在制作一个快递管理系统的项目

我有问题，如何计算2个城市或州之间的费率？以及如何将它存储在数据库中？..

请告诉我，我很困惑

i ''m just currently making a project which is courier management system
i have question that how to count rates between 2 city or state? and how to store it in db?..
please tell me i''m very confused

推荐答案

我也在同一个项目但在网上...



如果你想使用c ++那么如果文件系统你必须存储数据库（我无法解释）

我只是解释你我使用的是sql



快递费是由三个设定的类型..

1）区域明智

2）国家/地区

3）城市/邮政编码到城市/邮政编码



地区是一组国家。



我制作一张表来存储这些数据



couriercharge（id，fregionid，fcountryid，flocationid，tregionid，tcountryid，tlocationid，weightid，chargeamount）



f - 代表

t - 代表



你必须连接区域 - 国家和地点。

这里重量也考虑...

因为体重不同具有不同courrier率的范围



为0-1 kg可以每100 gm收取15 rs

1.001 -2.000 kg收费14 rs每100克等...



详细信息 - 你可以问一下你卡住的概念..

（如果你喜欢它请评价它&标记也有解决方案）
以上
只是介绍你看到的详细信息联邦快递，ups网站

谢谢

Hi,

I am also working same project but On web...

if you want to work with c++ then if filesystem you have to store database(which I cant explain)
I just explain you which I used sql

the courier charge are set by three type..
1) region wise
2) country to country
3) city/postcode to city/postcode

Region is group of countries.

I make a table to store these data

couriercharge (id, fregionid,fcountryid,flocationid,tregionid,tcountryid,tlocationid,weightid,chargeamount)

f - stand for from
t - stand for to

you have to connect region - country and location.
here weight also consider...
because different weight range having different courrier rate

as 0-1 kg may be charge by 15 rs per 100 gm
1.001 -2.000 kg charge by 14 rs per 100 gm etc...

For detail-- You can ask regarding the concept where you stuck..
(If you like it please rate it & mark also with solution)
above is just introduction of courrier charges you see for detail fedex ,ups website
Thanks

如果它只是一个玩具应用程序，那么您可以简单地根据距离计算费率城市，即双倍距离意味着双倍率等等。

例如，您的数据库可能包含一个矩阵，其中包含城市对之间的所有距离。

If it is just a toy application then you may computes rates simply based on distance between the cities, that is double distance implies double rate and so on.
Your database, for instance, could contain a matrix with all the distances between city pairs.
