案例背景：
大数据技术的应用可以从海量的用户行为数据中进行挖掘分析，根据分析结果优化平台的服务质量，最终满足用户的需求。教育大数据分析平台项目就是将大数据技术应用于教育培训领域，为企业经营提供数据支撑。
案例数据产生流程：
案例数据流转：
首先业务是存储在MySQL数据库中, 通过sqoop对MySQL的数据进行数据的导入操作, 将数据导入到HIVE的ODS层中, 对数据进行清洗转换成处理工作, 处理之后对数据进行统计分析, 将统计分析的结果基于sqoop在导出到MySQL中, 最后使用finebi实现图表展示操作, 由于分析工作是需要周期性干活, 采用ooize进行自动化的调度工作, 整个项目是基于cloudera manager进行统一监控管理
案例需求：
- 建立集团数据仓库，统一集团数据中心，把分散的业务数据进行预先处理和存储
- 根据业务分析需要，从海量的用户行为数据中进行挖掘分析，定制多维的数据集合，形成数据集市，供各个场景主题使用。
- 前端业务数据展示选择和控制，选取合适的前端数据统计、分析结果展示工具。
案例架构：
案例工具：
zookeeper: 集群管理工具, 主要服务于hadoop高可用以及其他基于zookeeper管理的大数据软件
HDFS: 主要负责最终数据的存储
YARN: 主要提供资源的分配HIVE: 用于编写SQL, 进行数据分析

总体分析：
涉及维度:
固有维度:
时间维度: 年 季度 月 天 小时
产品属性维度:
地区维度
来源渠道
搜索来源
受访页面涉及指标:
访问量
咨询量
涉及表 :
事实表: web_chat_ems_2019_12 和 web_chat_text_ems_2019_11
维度表: 没有 (数仓建模, 不需要DIM层)涉及字段:
时间维度:
web_chat_ems: create_time
地区维度:
web_chat_ems: area
来源渠道:
web_chat_ems: origin_channel
搜索来源:
web_chat_ems: seo_source
受访页面:
web_chat_text_ems: from_url
指标字段:
访问量: sid
咨询量: sid区分访问和咨询:
web_chat_ems: msg_count >= 1 即为咨询数据需要清洗数据: 没有清洗
需要转换字段: 时间字段
需要将create_time 转换为 yearinfo, quarterinfo,monthinfo,dayinfo,hourinfo
一对一关系 : id = id
一对一关系其实本质就是一张表
数据准备： 将原始数据加载到本地MySQL数据库中
访问客户量的数据来源于咨询系统的访问会话月表web_chat_ems：
表名的格式为web_chat_ems_年_月，年份为4位数字，月份为二位数字，如果为单数时，前面会用0来补全，比如web_chat_ems_2019_07
web_chat_text_ems表是访问附属月表：
表名的格式和web_chat_ems相同。web_chat_ems和web_chat_text_ems是一一对应的，通过主键id进行关联。
在当前数据库下执行sql脚本文件，将数据导入即可
建模分析：
ODS层: 源数据层
作用: 对接数据源, 一般和数据源保持相同的粒度(将数据源数据完整的拷贝到ODS层)
建表比较简单:
业务库中对应表有那些字段, 需要在ODS层建一个与之相同字段的表即可, 额外在建表的时候, 需要构建为分区表, 分区字段为时间字段, 用于标记在何年何月何日将数据抽取到ODS层
此层会有二个表
DIM层: 维度层
作用: 存储维度表数据
此时不需要, 因为当前主题, 没有维度表
DWD层: 明细层
作用: 1) 清洗转换 2) 少量维度退化
思考1: 当前需要做什么清洗操作?
不需要进行清洗思考2: 当前需要做什么转换操作?
需要对时间字段进行转换, 需要转换为 yearinfo, quarterinfo,monthinfo,dayinfo,hourinfo思考3: 当前需要做什么维度退化操作?
两个事实表合并在一起
建表字段 : 原有表的字段 + 转换后的字段+ 清洗后字段
sid,session_id,ip,create_time,area,origin_channel,seo_source,
from_url,msg_count,yearinfo,quarterinfo,monthinfo,dayinfo,
hourinfo,referrer,landing_page_url,url_title,
platform_description,other_params,history思想:
当合并表个表的时候, 获取抽取数据时候, 处理方案有三种:
1) 当表中字段比较多的时候, 只需要抽取需要用的字段
2) 当无法确定需要用那些字段的时候, 采用全部抽取
3) 如果表中字段比较少, 不管用得上, 还是用不上, 都抽取
DWM层: 中间层 (省略)
作用: 1) 维度退化操作 2) 提前聚合
思考1: 当前需要进行什么维度退化操作?
没有任何维度退化操作, 压根都没有DIM层
思考2: 当前需要进行什么提前聚合操作?
可以尝试先对小时进行提前聚合操作, 以便于后统计方便思考3: 当前主题是否可以按照小时提前聚合呢?
目前不可以, 因为数据存在重复的问题, 无法提前聚合, 一旦聚合后, 会导致后续的统计出现不精确问题
DWS层: 业务层
作用: 细化维度统计操作
一般是一个指标会对应一个统计结果表
访问量:
固有维度:
时间维度: 年 季度 月 天 小时
产品属性维度:
地区维度

搜索来源
受访页面建表字段: 指标统计字段 + 各个维度字段 + 三个经验字段(time_type,group_time,time_str)
sid_total,sessionid_total,ip_total,yearinfo,quarterinfo,monthinfo,dayinfo,hourinfo,
area,origin_channel,seo_source,from_url, time_type,group_time,time_str咨询量:

area,origin_channel, time_type,group_time,time_str
注意: 如果不存在的维度字段的值, 设置为 -1 (业务指定, 表示没有这个维度)
DA层:
作用: 对接应用, 应用需要什么数据, 从DWS层获取什么数据即可
此层目前不做任何处理, 已经全部需要都细化统计完成了, 后续具体用什么, 看图表支持了...
建模操作（建表）：

目的: 将ODS层数据导入到DWD层
DWD层作用:
1) 清洗转换操作 2) 少量维度退化操作思考1: 是否需要做清洗转换操作, 如果需要做什么呢?
清洗操作: 不需要
转换操作: 将create_time日期 转换为 yearinfo quarterinfo monthinfo dayinfo hourinfo
额外加一个转换: 将create_time日期数据转换为时间戳
思考2: 是否需要进行维度退化操作, 如果需要做什么呢?
需要的, 将两个事实表合并称为一个事实表

数据导出
目的: 从hive的DWS层将数据导出到mysql中对应目标表中
第一步: 在mysql中创建目标表:创建数据库建表
create database scrm_bi default character set utf8mb4 collate utf8mb4_general_ci; -- 访问量的结果表: CREATE TABLE IF NOT EXISTS scrm_bi.visit_dws ( sid_total INT COMMENT '根据sid去重求count', sessionid_total INT COMMENT '根据sessionid去重求count', ip_total INT COMMENT '根据IP去重求count', area varchar(32) COMMENT '区域信息', seo_source varchar(32) COMMENT '搜索来源', origin_channel varchar(32) COMMENT '来源渠道', hourinfo varchar(32) COMMENT '创建时间，统计至小时', time_str varchar(32) COMMENT '时间明细', from_url varchar(1000) comment '会话来源页面', groupType varchar(32) COMMENT '产品属性类型：1.地区；2.搜索来源；3.来源渠道；4.会话来源页面；5.总访问量', time_type varchar(32) COMMENT '时间聚合类型：1、按小时聚合；2、按天聚合；3、按月聚合；4、按季度聚合；5、按年聚合；', yearinfo varchar(32) COMMENT '年' , quarterinfo varchar(32) COMMENT '季度', monthinfo varchar(32) COMMENT '月', dayinfo varchar(32) COMMENT '天' )comment 'EMS访客日志dws表'; -- 咨询量的结果表: CREATE TABLE IF NOT EXISTS scrm_bi.consult_dws ( sid_total INT COMMENT '根据sid去重求count', sessionid_total INT COMMENT '根据sessionid去重求count', ip_total INT COMMENT '根据IP去重求count', area varchar(32) COMMENT '区域信息', origin_channel varchar(32) COMMENT '来源渠道', hourinfo varchar(32) COMMENT '创建时间，统计至小时', time_str varchar(32) COMMENT '时间明细', groupType varchar(32) COMMENT '产品属性类型：1.地区；2.来源渠道', time_type varchar(32) COMMENT '时间聚合类型：1、按小时聚合；2、按天聚合；3、按月聚合；4、按季度聚合；5、按年聚合；', yearinfo varchar(32) COMMENT '年' , quarterinfo varchar(32) COMMENT '季度', monthinfo varchar(32) COMMENT '月', dayinfo varchar(32) COMMENT '天' )COMMENT '咨询量DWS宽表';第二步执行sqoop的数据导出
-- 先导出 咨询量数据 sqoop export \ --connect "jdbc:mysql://192.168.52.150:3306/scrm_bi?useUnicode=true&characterEncoding=utf-8" \ --username root \ --password 123456 \ --table consult_dws \ --hcatalog-database itcast_dws \ --hcatalog-table consult_dws \ -m 1 -- 访问量数据导出 sqoop export \ --connect "jdbc:mysql://192.168.52.150:3306/scrm_bi?useUnicode=true&characterEncoding=utf-8" \ --username root \ --password 123456 \ --table visit_dws \ --hcatalog-database itcast_dws \ --hcatalog-table visit_dws \ -m 1访问和咨询用户数据模块（增量分析）：
模拟新增数据，实际生产过程中由需求方自行提供新增数据：
-- 模拟访问咨询主表数据 CREATE TABLE web_chat_ems_2021_09 AS SELECT * FROM web_chat_ems_2019_07 WHERE create_time BETWEEN '2019-07-01 00:00:00' AND '2019-07-01 23:59:59'; -- 修改表中的时间字段 UPDATE web_chat_ems_2021_09 SET create_time = CONCAT('2021-09-25 ',SUBSTR(create_time,12)); -- 模拟访问咨询附属表数据 CREATE TABLE web_chat_text_ems_2021_09 AS SELECT temp2.* FROM (SELECT * FROM web_chat_ems_2019_07 WHERE create_time BETWEEN '2019-07-01 00:00:00' AND '2019-07-01 23:59:59') temp1 JOIN web_chat_text_ems_2019_07 temp2 ON temp1.id = temp2.id ;增量数据采集：
将增量的SQL集成到增量的sqoop脚本中，通过shell脚本的方式来执行, 通过脚本自动获取上一天的日期, 最后将shell脚本放置在ooize中, 进行自动化调度操作
编写增量数据采集的shell脚本
hadoop01: 家目录
cd /root
vim edu_mode_1_collect.sh
edu_mode_1_collect.sh脚本：此脚本能够实现自动获取上一天的日期数据, 并且还支持采集指定日期下数据，将shell脚本放置到ooize中,完成自动化调度操作。
#!/bin/bash export SQOOP_HOME=/usr/bin/sqoop if [ $# == 1 ] then dateStr=$1 else dateStr=`date -d '-1 day' +'%Y-%m-%d'` fi dateNowStr=`date +'%Y-%m-%d'` yearStr=`date -d ${dateStr} +'%Y'` monthStr=`date -d ${dateStr} +'%m'` jdbcUrl='jdbc:mysql://192.168.52.150:3306/nev' username='root' password='123456' m='1' ${SQOOP_HOME} import \ --connect ${jdbcUrl} \ --username ${username} \ --password ${password} \ --query "SELECT id,create_date_time,session_id,sid,create_time,seo_source,seo_keywords,ip, AREA,country,province,city,origin_channel,USER AS user_match,manual_time,begin_time,end_time, last_customer_msg_time_stamp,last_agent_msg_time_stamp,reply_msg_count, msg_count,browser_name,os_info, '${dateNowStr}' AS starts_time FROM web_chat_ems_${yearStr}_${monthStr} WHERE create_time BETWEEN '${dateStr} 00:00:00' AND '${dateStr} 23:59:59' and \$CONDITIONS" \ --hcatalog-database itcast_ods \ --hcatalog-table web_chat_ems \ -m ${m} ${SQOOP_HOME} import \ --connect ${jdbcUrl} \ --username ${username} \ --password ${password} \ --query "SELECT temp2.*, '${dateNowStr}' AS start_time FROM (SELECT id FROM web_chat_ems_${yearStr}_${monthStr} WHERE create_time BETWEEN '${dateStr} 00:00:00' AND '${dateStr} 23:59:59') temp1 JOIN web_chat_text_ems_${yearStr}_${monthStr} temp2 ON temp1.id = temp2.id where 1=1 and \$CONDIT IONS" \ --hcatalog-database itcast_ods \ --hcatalog-table web_chat_text_ems \ -m ${m}测试脚本是否可以正常执行
sh edu_mode_1_collect.sh 可以在hive中查看对应分区下的数据, 如果有, 说明抽取成功了 select * from itcast_ods.web_chat_ems where starts_time='2021-09-26' limit 10;注意：starts_time是当天抽取的当天日期，抽取的数据库中的表的数据是前一天的，所以建表的时候要把ceratetimes字段改为前一天的。比如今天是2021-09-26，我创建的表的名字是
也可以在抽取表的时候带上日期参数，这样可以随机抽取任意一天的数据。
将shell脚本放置到ooize中,完成自动化调度操作 
增量数据清洗转换
仅需要对新增的这一天数据进行清洗转换操作，因为此时数据粒度是一致的，不需要对之前的数据做处理。
在shell下执行hive的SQL
./hive -e|-f 'sql语句|SQL脚本' -S编写shell脚本, 实现增量数据清洗转换操作
hadoop01:
cd /root
vim edu_mode_1_handle.sh
#!/bin/bash export HIVE_HOME=/usr/bin/hive if [ $# == 1 ] then dateStr=$1 else dateStr=`date +'%Y-%m-%d'` fi sqlStr=" set hive.exec.dynamic.partition=true; set hive.exec.dynamic.partition.mode=nonstrict; set hive.exec.compress.intermediate=true; set hive.exec.compress.output=true; set hive.exec.orc.compression.strategy=COMPRESSION; insert into table itcast_dwd.visit_consult_dwd partition(yearinfo,quarterinfo,monthinfo,dayinfo) select wce.session_id, wce.sid, unix_timestamp(wce.create_time) as create_time, wce.seo_source, wce.ip, wce.area, wce.msg_count, wce.origin_channel, wcte.referrer, wcte.from_url, wcte.landing_page_url, wcte.url_title, wcte.platform_description, wcte.other_params, wcte.history, substr(wce.create_time,12,2) as hourinfo, substr(wce.create_time,1,4) as yearinfo, quarter(wce.create_time) as quarterinfo, substr(wce.create_time,6,2) as monthinfo, substr(wce.create_time,9,2) as dayinfo from (select * from itcast_ods.web_chat_ems where starts_time='${dateStr}') wce join (select * from itcast_ods.web_chat_text_ems where start_time='${dateStr}') wcte on wce.id = wcte.id; " ${HIVE_HOME} -e "${sqlStr}" -S测试脚本：
sh edu_mode_1_handle.sh测试数据是否产生:
select * from itcast_dwd.visit_consu1t_dwd where yearinfo='2024' and monthinfo='05'and dayinfo='23 '------这里测试的是数据产生的数据，也就是前一天的数据，日期是从create分出来的
配置工作流：
增量数据统计分析
第一张表25个需求，第二张表15个需求，有点多， 各选5条模拟一下：
访问量：5条
-- 统计每年的总访问量
-- 统计每年每季度的总访问量
-- 统计每年每季度每月的总访问量
-- 统计每年每季度每月每天的总访问量
-- 统计每年每季度每月每天每小时的总访问量
咨询量: 5条
-- 统计每年各个地区的咨询量-- 统计每年每季度各个地区的咨询量
-- 统计每年每季度每月各个地区的咨询量
-- 统计每年每季度每月每天各个地区的咨询量
-- 统计每年每季度每月每天每小时各个地区的咨询量
dwd表是新增了上一天的数据，统计年的就把今年的全部统计，月的把这个月的全部统计，不是就统计前一天的，所以将昨天的数据加入后再统计一遍年的，月的，季度的，以此类推……
说明：
在统计年的时候, 只需要统计加上这一天以后这一年的数据即可, 之前年的数据是不需要统计的
在统计季度的时候,只需要统计加上这一天以后这一年对应的这一季度的数据即可, 之前的季度是不需要统计的
在统计月份的时候, 只需要统计加上这一天以后这一年对应的这一月份的数据即可,之前的月份不需要统计
在统计天的时候, 只需要统计新增的这一天即可
在统计小时的时候, 只需要统计新增的这一天的每个小时
思考: 在统计的过程中, 比如以年统计, 得到一个新的年的统计结果, 那么在DWS层表中是不是还有一个历史的结果呢? 如何解决呢？
比如今天是2024-5-4，昨天已经统计了今年的数据了，今天又统计一遍，需要把昨天的历史数据删除，但hive不支持个别数据的删除。
说明:
在统计的过程中, 会对之前的统计结果产生影响, 主要受影响:年，季度，月
注意: 天 和 小时是不受历史结果影响解决方案:
将之前的结果受影响的结果值删除即可如何删除呢? 注意hive不支持直接对表中某条数据删除
可以通过删除分区的方案进行处理思考:
当年的统计结构数据在那个分区下存储着呢?此分区了存储了按年统计的各个产品属性维度的结果数据
yearinfo='2021' and quarterinfo='-1' and monthinfo ='-1' and dayinfo='-1'
此分区存储了当年当季度的统计数据
yearinfo='2021' and quarterinfo='3' and monthinfo ='-1' and dayinfo='-1'
此分区存储了当年当季度当月的统计数据
yearinfo='2021' and quarterinfo='3' and monthinfo ='09' and dayinfo='-1'执行删除:
alter table xxx drop partition(yearinfo='2021' and quarterinfo='-1' and monthinfo ='-1' and dayinfo='-1');
alter table xxx drop partition(yearinfo='2021' and quarterinfo='3' and monthinfo ='-1' and dayinfo='-1');
alter table xxx drop partition(yearinfo='2021' and quarterinfo='3' and monthinfo ='09' and dayinfo='-1');注意：先删后加！！！

增量数据导出操作
说明：
在执行导出的时候, 也需要将mysql中之前的统计的当年当季度和当月的结果数据删除, 然后重新导入操作
此时我们处理的方案, 要进行简化一些, 受影响最大范围当年的数据, 可以直接将当年的统计结果数据全部都删除, 然后重新到DWS层当年的所有数据，就是将当年的那个分区数据导出即可。（MySQL可以直接删除）
