The **Data Management** tab of the **Communications** window provides functionality for storing and managing all data associated with your motion capture files. Data is organized in a hierarchical structure, with data and information stored in relevant nodes.

For a video guide to database management, see the Vicon video, [proEclipse: Preparing and managing your database](https://www.youtube.com/watch?v=rZh-R7eHwcg&feature=youtu.be).

The default location of **Data Management** is on a tab at the bottom of the **Communications** window. If you prefer, you can click the buttons at the top right of the **Communications** window to un-dock it and display it full-screen. To toggle the display of the Data Management tab, press F2.

> ✅ **Tip**   
> ✅ You can also choose to hide the entire **Communications** pane, in which the **Data Management** tab appears, when you load a trial. To do this, on the **Window** menu, select the **Close Communications Pane on Trial Load** option. Alternatively, to temporarily hide/reveal the **Communications** pane, double-click any of its tabs.

By default, the last opened database is loaded when you restart Nexus.

> ⚠️ **Offline Data Management/ProEclipse display**  
> ⚠️ In Nexus 2.20 and later, if you access Data Management offline (ie, when you’re not connected to the internet), you may find that it is displayed as a gray tab with a small circle on it. To restore its normal appearance and behavior, follow the steps in [Install the Microsoft loopback adapter](https://vicon-help.atlassian.net/wiki/spaces/Nexus220/pages/897714887/Set+up+Python+for+use+with+Nexus#InstallLBAdapter).
