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.
The Data connections overview lists all the available data connections.
By default, the QMC contains two data connections: ArchivedLogsFolder and ServerLogFolder. These are the data connections for the two monitoring apps, License Monitor and Operations Monitor, which are installed together with the QMC. For users with admin roles (root, security, content, and deployment), the data connections are available in the data load editor in the Qlik Sense hub.
The following table presents the available fields and buttons. By default, only some of the fields are displayed. You can use the column selector (') to add fields.
|Name||The name of the data connection.|
|Owner||The owner of the data connection.|
|Tags||The tags that are connected to the data connection.|
