一、背景介绍
Adventure Works Cycles是Adventure Works样本数据库所虚构的公司，这是一家大型跨国制造公司。该公司生产和销售自行车到北美，欧洲和亚洲的商业市场。虽然其基地业务位于华盛顿州博塞尔，拥有290名员工，但几个区域销售团队遍布整个市场。
二、分析目的
分别从整体，地域，产品，用户以及热销产品五个方面展开分析，为公司的制造和销售提供指导性建议，以增加公司的收益。
三、分析框架

四、分析过程
准备工作：
# 导入模块
import pandas as pd
import numpy as np
1. 自行车的整体销售表现情况
1.1 自行车整体销量表现
# 导入数据
gather_customer_order=pd.read_csv("dw_customer_order.csv")
gather_customer_order.info()
image.png
#增加create_year_month月份字段。按月维度分析时使用
gather_customer_order['create_year_month']=gather_customer_order['create_date'].apply(lambda x:x.strftime('%Y-%m'))
#筛选产品类别为自行车的数据
gather_customer_order = gather_customer_order[gather_customer_order['cplb_zw'] == '自行车']
#获取每月订单数量和销售金额，用groupby创建一个新的对象，需要将order_num、sum_amount求和
overall_sales_performance = gather_customer_order.groupby('create_year_month').agg({'order_num':'sum','sum_amount':'sum'}).sort_index(ascending = False).reset_index()
overall_sales_performance.head()
image.png
# 求销量的环比：
# 增加一列将销量按照日期顺序向后移动与当月的销量相除求得环比
order_num_diff = list(overall_sales_performance['order_num'].diff()/overall_sales_performance['order_num']/-1)
order_num_diff.pop(0)
order_num_diff.append(0)
#将环比转化为DataFrame，添加至表中
overall_sales_performance = pd.concat([overall_sales_performance,pd.DataFrame({'order_num_diff':order_num_diff})],axis = 1)
overall_sales_performance.head()
image.png
1.2 自行车整体销售额表现
#求每月自行车销售金额环比
sum_amount_diff = list(overall_sales_performance['sum_amount'].diff()/overall_sales_performance['sum_amount']/-1)
sum_amount_diff.pop(0) #删除列表中第一个元素
sum_amount_diff.append(0) #将0新增到列表末尾
sum_amount_diff
#将环比转化为DataFrame，添加至表中
overall_sales_performance = pd.concat([overall_sales_performance,pd.DataFrame({'sum_amount_diff':sum_amount_diff})],axis = 1)
#查看每月自行车订单量、销售金额、环比
overall_sales_performance.head(5)

#按照区域、月分组,订单量求和，销售金额求和
gather_customer_order_10_11_group= gather_customer_order_10_11.groupby(['chinese_territory','create_year_month']).agg({'order_num':'sum','sum_amount':'sum'}).reset_index()
根据区域对数据进行偏移求各区域销量与销售额环比
#将区域存为列表

5. 用户行为分析
获取数据
# 读取数据库客户信息表
df_CUSTOMER_order=pd.read_csv("ods_customer.csv")
# 读取数据库销售订单表
df_sales_orders_11=pd.read_csv("ods_sales_orders.csv")
# 改变数据格式
df_sales_orders_11['customer_key'] = df_sales_orders_11['customer_key'].astype("int")
# 将两表关联
sales_customer_order_11=pd.merge(df_sales_orders_11,df_CUSTOMER,on='customer_key',how='left')
# 通过出生日期，分解选取年份，删除月日
customer_birth_year = sales_customer_order_11['birth_date'].str.split('-',expand = True).rename(columns = {0:'birth_year'}).drop(labels = [1,2],axis = 1)
sales_customer_order_11 = pd.concat([sales_customer_order_11,customer_birth_year],axis = 1)

image.png
5.1 用户年龄分析
通过出生日期计算年龄，同时对年龄分层
# 为birth_year列填充Null值，计算出年龄
sales_customer_order_11['birth_year'].fillna(0,inplace = True)
sales_customer_order_11['birth_year'] = sales_customer_order_11['birth_year'].astype('int')
sales_customer_order_11['customer_age'] = 2019 - sales_customer_order_11['birth_year']
# 根据年龄分层
sales_customer_order_11['age_level'] = pd.cut(sales_customer_order_11['customer_age'],[30,35,40,45,50,55,60,65],labels = ['30-34','35-39','40-44','45-49','50-54','55-59','60-64'])
sales_customer_order_11.head()
image.png
添加年龄比率列，对这列根据不同维度聚合可得到不同维度的占比
#筛选销售订单为自行车的订单信息
df_customer_order_bycle = sales_customer_order_11.loc[sales_customer_order_11['cplb_zw'] == '自行车']
# 计算年龄比率
df_customer_order_bycle['age_level_rate'] = 1/len(df_customer_order_bycle)
将年龄再次分组
#将年龄分为3个层次 # 用到了选取行列，然后给行列传值的方法
df_customer_order_bycle.loc[(df_customer_order_bycle['customer_age'] <= 29),'age_level2'] = '<=29'
df_customer_order_bycle.loc[(df_customer_order_bycle['customer_age'] >= 30)&(df_customer_order_bycle['customer_age'] <= 39),'age_level2'] = '30-39'
df_customer_order_bycle.loc[(df_customer_order_bycle['customer_age'] >= 40),'age_level2'] = '>=40'
# 求每个年龄段的人数
age_level2_count = df_customer_order_bycle.groupby(by = 'age_level2').sales_order_key.count().reset_index()
# 连接到大表中
df_customer_order_bycle = pd.merge(df_customer_order_bycle,age_level2_count,on = 'age_level2').rename(columns = {'sales_order_key_y':'age_level2_count'})
df_customer_order_bycle['age_level2_rate'] = 1/df_customer_order_bycle['age_level2_count']
5.2 用户性别分析
按性别分组聚合，添加至大表
df_customer_order_bycle = pd.merge(df_customer_order_bycle,gender_count,on = 'gender').rename(columns = {'cplb_zw_y':'gender_count'})
df_customer_order_bycle['gender_rate'] = 1/df_customer_order_bycle['gender_count']
5.3 导出数据并用PowerBI作图
