背景

实现动态表单功能，支持表单自定义并实现后期的数据统计、分析。

方案讨论

• 一 、基于非结构化的Json。
  • 优点：通过NoSql的mongdb存储可以减少json解析的复杂度及资源损耗，可以提高效率。
  • 缺点：非结构化的Json，模板定义和表单数据值存在一起，后期的数据分析非常困难。解决不了非结构化数据分析的根本问题。

• 二 、基于jeecg/ruoyi-低代码开发平台
  • 比较固定的样式 和表定义
  • 针对自己需求坐二次开发改动较大
  • 表比较多涉及功能广，跟原需求出入较大，不好扩展。

基于上面分析，对比调研，自定义动态表单

• 自定一表单数据结构。
• 内容展示如有必要行转列。

数据模型

表单详解

select * from jim_dynamic_form where form_name = '调研问卷A'; -- 表单-调研问卷A
select * from jim_form_data_type ; -- 表单-数据类型select * from jim_form_column where form_id = 1; -- 表单-调研问卷A的定义select * from jim_form_data where form_id = 1 and data_id = 1 ; -- 表单-调研问卷A的数据记录1-- 表单数据统计
select 
(select data_value from jim_form_data_detail where data_id = t.data_id and column_id = 1) as `姓名`, 
(select data_value from jim_form_data_detail where data_id = t.data_id and column_id = 2) as `年龄`,
(select data_value from jim_form_data_detail where data_id = t.data_id and column_id = 3) as `性别`,
(select data_value from jim_form_data_detail where data_id = t.data_id and column_id = 4) as `出生日期`from jim_form_data t where t.form_id = 1 and t.data_id = 1 ;

（一） 表单模板：jim_dynamic_form

（二）表单数据类型：jim_form_data_type

（三）表单字段定义：jim_form_column

（四）表单数据记录：jim_form_data

（五）表单数据统计：jim_form_data_detail

自定一组件

• 前端根据题目类型自定义组件
• 后端根据题目类型用策略模式校验各种类型

总结

• 这样有统计功能的简单动态问卷就可以了
• 展示时可能某些场景需要行转列。
• 大概估摸使用的话有可能jim_form_data_detail表的记录数比较大，后期再考虑数据或者表迁移或拆分。
