Connect with db files

In this section, you will learn how to connect the microfading package with the database files, that you created using the msdb package (see msdb - create db files).

Follow the instructions below:

open a new or an existing notebook
import the microfading package
```
import microfading as mf
```
In a new cell, run the following code:
```
mf.set_DB()
```
This will display some ipywidgets (see figures below). If you click on inside the white space rectangle for the db_name and then push the bottom arrow on your keyboard, a window should appear with the name of the database files that you previously created. You can then select one of the names, and the db_path will automatically be filled with the valid value.

The parameter called Use defines whether the microfading package should by default make us the information provided in the database files. By default it is set to True, and you can leave it as it is. But you can decide to still make the connection between the microfading package and the database files and decide manually each time you want the functions of the microfading package to make use the database files.
