What kind of information is going into the database?
How will the data to get there?
How do you want the data to be displayed? Formatted?
I would start with a basic example first to understand how to the database will work.
Create a text box
User types in text to the text box
User clicks a button
Text is inserted into database
A different text block is connected to the database.
Reviewing this article first will likely help.

A very generic example below for inserting data from text box to database.
function button_click(event){
let newDatabaseEntry = {
‘info’ : $w( ‘#MyTextBox’ ).value,
}
wixData.insert( 'MyDatabase' , newDatabaseEntry );
}
