Mongo database is not created using mongoose

I want to create a database with the schema created in my data.js file but the database doesn't get created

index.js:

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var path = require('path'); 
var expressValidator = require('express-validator');
var mongoose = require('mongoose');
var Data = require('./models/data');

mongoose.connect('mongodb://localhost:27017/data');
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'mongodb connection 
error'));
db.once('open', () => console.log('mongodb connected'));

//app.use(expressValidator(customValidators));
app.use(express.static(path.join(__dirname,'public')));
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: true }));

app.get('/',function(req,res){
    var d = new Data({optionName:"switchOnLights",optionValues:
                                             ["switchOnLights"]});
    d.save(err =>{console.error(err)});
    res.render('index');
});

app.post('/users/add',function(req,res){
   var text = req.body.text;
   var option = req.body.option; 
   db.Data.update(
    {optionName:option},
    {$addToSet:{optionValues:text}})
});

app.listen(3001,function(){
  console.log("server is running");
})

data.js (my model):

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

var dataSchema = new Schema({
   optionName:String,
   optionValues:[{type:String}]
});
var Data = mongoose.model('Data',dataSchema);
module.exports = Data;

I also tried testing the database by adding a new document when accessing the homepage but it still didn't create the database

You should first create an instance of model then save it to the database. Instead of

db.Data.update()

try the following code block:

var d = new Data({//columns});
d.save(err => {//handle errors});

for more information you can have a look at mongoos official docs
