If you often need to handle data of a MongoDB database, then you may want to centralize the connection to the database and the schema details in the Metadata folder in the Repository tree view.

The MongoDB metadata setup procedure is made of two separate but closely related major tasks:

1. Create a connection to a MongoDB database.

2. Retrieve MongoDB schemas of interest.

Prerequisites:

* All the required external modules that are missing in Talend Studio due to license restrictions have been installed. For more information, see [Installing external modules to Talend Studio](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/installing-external-modules).
