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.

Uwaga: 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.
Porada: To give access to the data connection to other users than the owner, edit the connection or go the Security rules page.

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.

Uwaga: If the Data connections overview contains a connection called DM, that connection is for Qlik DataMarket internal use.

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.

Porada: You can adjust the column width by dragging the header border.

Owner The owner of the data connection.
