accessing wixData from backend module

What i’m doing wrong can you suggest me the code:

Backend Code:

import { fetch } from 'wix-fetch';
import wixData from 'wix-data';

export async function getData() {

 const apiKey = "xxxxxxxxxxxxxxxxx";
 //const id = "xxxxxxxxxxxxxxxx"; (it works when i declare this but i want to take values from my database)
 let id = wixData.get('myDatabaseName'.'title');
 

 const response = await fetch("https://www.exampleapis.com/&id=" + id + "&key=" + apiKey, {
        method: 'get'
    });

Frontend code:

 
import { getData } from 'backend/datacall.jsw';


$w.onReady(function () {

    getData()
        .then((response) => {
 //let subCount = response.items[0].example;
 let fName = response.items[0].example.title;
            $w("#pName").text = fName;
        });

});
