Managing data connections and extensions

Data connections

Data connections enable you to select and load data from a data source. All data connections are managed centrally from the QMC. Data connections are created in the Qlik Sense data load editor. The user who creates a data connection automatically becomes the owner of that connection and is by default the only user who can access the data connection. The data connection can be shared with others through security rules defined in the QMC.

When you import an app developed on Qlik Sense Desktop, existing data connections are imported to the QMC. When you export an app from a server, existing data connections are not exported with the app.

备注: If the name of a data connection in the imported app is the same as the name of an existing data connection, the data connection will not be imported. This means that the imported app will use the existing data connection with an identical name, not the data connection in the imported app.

Analytic connections

借助分析连接,您将能够将外部分析与商业探索集成。分析连接扩展您可在加载脚本和图表中使用的表达式,方法是调用外部计算引擎(当您如此操作时,计算引擎用作服务器端扩展 (SSE))。例如,您可创建指向 R 的分析连接,并在加载数据时使用统计表达式。


Extensions can be several different things: A widget library, a custom theme, or a visualization extension, used to visualize data, for example, in an interactive map where you can select different regions.
