1.Python爬虫采集物流数据等存入mysql和.csv文件;
2.使用pandas+numpy或者MapReduce对上面的数据集进行数据清洗生成最终上传到hdfs;
3.使用hive数据仓库完成建库建表导入.csv数据集;
4.使用hive之hive_sql进行离线计算,使用spark之scala进行实时计算;
5.将计算指标使用sqoop工具导入mysql;
6.使用Flask+echarts进行可视化大屏实现、数据查询表格实现、含预测算法;
核心算法代码分享如下:
- from flask import Flask, request

- #row_headers = [x[0] for x in cur.description] # this will extract row headers
- row_headers = ['name','goods','bads'] # this will extract row headers
- rv = cur.fetchall()
