+## Introduction
+<!-- DOCS_DESCRIPTION_CN -->
+本示例用于实现解决方案[一站式时空决策，释放空间数据价值](https://www.aliyun.com/solution/tech-solution/datav-for-atlas)，涉及专有网络（VPC）、交换机（VSwitch）、RDS数据库（RDS）等资源的部署。
+<!-- DOCS_DESCRIPTION_CN -->
+
+<!-- DOCS_DESCRIPTION_EN -->
+This example is used to implement solution [Unified spatio-temporal decision-making to unlock the value of spatial data](https://www.aliyun.com/solution/tech-solution/datav-for-atlas), which involves the creation and deployment of resources such as Virtual Private Cloud (VPC), Virtual Switch (VSwitch),RDS Database (RDS).
