数据准备
Demo 数据
在 需求描述 场景下，我们准备使用 MySQL 数据库作为数据源。TCBI 系统已经默认为用户提供了员工数据源示例，如下所示：
具体的数据源信息见：员工数据源示例。
建议使用此数据源，可以忽略下面的步骤，直接到下一小节 数据建模。
新建数据源
如果希望新建自己的数据源信息，可以参考如下操作。
通过选择 TCBI概览页 > 数据连接，创建数据库连接：n第一步：n
﻿
n第二步：n
﻿
﻿
注意事项
如果连接测试不通过，请通过如下几个步骤进行排查：
1. 公网域名可正常解析，公网 IP 地址和端口可正常访问。
2. 数据库 IP 白名单设置，查看 腾讯云图数据可视化数据代理 IP 白名单。
3. 数据库已启动，且未被防火墙禁止访问。
