JSON 已经成为系统集成标准的数据通信方式,在很多场景中都有重要的应用,比如:
前后端分离开发时,数据在后端处理好通过 API 将 JSON 返回给前端页面
SaaS 产品对外通过 Web API 返回 JSON 提供数据服务,而不是让用户直接连接到数据库(因为这样不能确保安全性,而且数据库服务通常是多租户公用,无法直接登录访问)
数据中台已经得到广泛应用,中台通过对后台复杂的数据环境进行服务化封装,用户可以通过 API 轻松获得数据服务,进行数据查询操作。
IoT 物联网平台,通常也是通过 API 对外提供数据查询服务,而不是直接连接数据库环境进行查询。
在产品中,对 JSON 与 API 的数据对接功能有了极大增强,可以对 JSON 数据源像使用数据库一样进行灵活的查询分析,而且不用写 SQL 语句。比如:对 JSON 数据进行同比、环比、占比、排名等智能分析。也可以在仪表板中使用分析表达式进行更多灵活的查询操作。
在仪表板中可以直连 WEB JSON ,更多详情请见直连 WEB JSON(JSON API数据)。
