# Data Viewer Manual

In the Hengshi system, a data viewing role is designed for business personnel, and only those with the data viewing role are considered data viewers. After logging into the system, data viewers can only access the [Home](home.md) and [App Market](app-analyst-market.md) modules. The Home module only displays content related to the App Market.

In the App Market module, applications published by other users are displayed. Data viewers can view these applications, including [View Data](app-publish.md#查看数据), [Export Data](app-publish.md#导出数据), [Export Application Template](app-publish.md#导出模板), and can also [Embed and Share](publish-analyst-share-embed.md) these applications and charts within them.

The [View Data](app-publish.md#查看数据), [Export Data](app-publish.md#导出数据), and [Export Application Template](app-publish.md#导出模板) functionalities require the application publisher to set the relevant permissions during application publishing; otherwise, these operations cannot be performed.
