互联网营销精准决策项目总结

时间:2019-09-11 12:21:04      阅读:77      评论:0      收藏:0      [点我收藏+]

  在今天我已经吧互联网营销精准决策项目的所有数据处理和分析的工作都完成了,包括按照范围分类,给表格打标签,设置权重,添加宽表,价格分类分析,销售情况分类分析等

  在这几天的开发过程中,自己学到了很多,包括一些hive的使用方式、hql的语法,jdbc对hive的连接,hive的运行体制等,更重要是根据老师给的需求一步步自己探索,让我对数据分析有了一个新的认知,知道了拿到怎样的数据应该按照怎样的步骤,按照怎么样的范围去划分数据去分类去分析。

  下面附上我的具体操作代码,其中有基本的注释,但由于写的过程中太投入了,就没有截图。。。。。。

  以下代码的总结主要是用于以后自己在写hive时回顾,对于一些小白就算没有数据集也可以看一些基本的语法,很多代码还可以优化,但毕竟我刚开始学,多多包涵。
