How to create database table in titanium by using model?

I have below 2 approach to create Db table in titanium.

Approach 1 -- Create a sqlite database, using queries in the titanium code. like Ti.Database.open("DBName"); and then create tables using sqlite queries

var db = Ti.Database.open('DBName');

db.execute('CREATE TABLE IF NOT EXISTS test(id INTEGER PRIMARY KEY, name TEXT)');

Its working fine.

But i need to know how to create table by using model

Approach 2 -- Create database Ti.Database.open("DBName");

Create model book.js and here is the code

exports.definition = {
    config: {


        "columns": {
            "id":"TEXT PRIMARY KEY",
            "title":"TEXT  ",
            "author":"TEXT",
        },

        adapter: {
            type: "sql",
            collection_name: "book"
        }
    },
    extendModel: function(Model) {
        _.extend(Model.prototype, {
            // extended functions and properties go here
        });

        return Model;
    },
    extendCollection: function(Collection) {
        _.extend(Collection.prototype, {
            // extended functions and properties go here
        });

        return Collection;
    }
};

Now I am in little bit confusion for creating table using model.

Please help and guide me for creating table.

If the adapter type="sql" then your DB is automatically created.

If you're using models, you no longer need to worry about opening the DB etc.

From the Alloy_Collection_and_Model_Objects, create a model and save it to DB:

var book = Alloy.createModel('book', {title:'Green Eggs and Ham', author:'Dr. Seuss'}); 
book.save();

To load data back from the DB:

var books = Alloy.Collections.instance('books');
var filteredArray = books.where({book_id: args.bookId});

Study the Alloy_Collection_and_Model_Objects and the Backbone JS docs
