# Data manager

Add data from data sources in Data manager and then preview and associate the data. Perform other actions, such as add calculated fields. When you are done, load the data.

Click Data manager in the application navigation menu to open Data manager.

Associations is the default view. You can also select Tables view.

If you have not added data to your application, you are instead prompted to do so before you can associate the data.

In both views you can:

* Add data and load data. Add data to Qlik Sense to preview and perform actions on the data, and then load the data. You can also reload data. See: [Adding data to the application from connections and new files](https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/LoadData/adding-data.htm)

* Concatenate or join tables: See: [Concatenating tables in Data manager](https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/LoadData/concatenating-tables-in-data-manager.htm), [Joining tables in Data manager](https://help.qlik.com/en-US/cloud-services/Subsystems/Hub/Content/Sense_Hub/LoadData/join-keep-tables-in-data-manager.htm)
