HDFS中存储再通过Spark、Spark SQL完成清洗、聚合和统计分析Python版本用Django做后端Java版本用Spring Boot做后端结果落到MySQL前端用Vue、ElementUI、Echarts、HTML、CSS、JavaScript和jQuery做页面展示。系统首页负责整体导航数据大屏集中展示饮水健康关键指标饮水健康数据模块维护原始记录活动程度分析观察不同活动量下的饮水差异体格因素分析结合身高体重等指标看饮水需求人口结构分析按年龄、性别等维度做对比水分状况分析判断每日补水是否合理综合洞察分析汇总多个分析结果天气影响分析结合天气情况看饮水变化个人信息和修改密码用于账号维护。整体重点在大数据处理和可视化呈现适合作为计算机专业毕设参考。二、开发环境大数据框架HadoopSpark本次没用Hive支持定制开发语言PythonJava两个版本都支持后端框架DjangoSpring Boot(SpringSpringMVCMybatis)两个版本都支持前端VueElementUIEchartsHTMLCSSJavaScriptjQuery详细技术点Hadoop、HDFS、Spark、Spark SQL、Pandas、NumPy数据库MySQL三、系统界面展示基于大数据的饮水健康行为分析与可视化研究系统界面展示四、部分代码设计项目实战-代码参考frompyspark.sqlimportSparkSessionfrompyspark.sql.functionsimportcol,whenfromdjango.httpimportJsonResponse
