Sqlite db not created in ionic

Hi all,
I am trying to create a ionic application which will interact with sqlite.
I followed this video for db interaction https://www.youtube.com/watch?v=Nn5RQpZBDsg.
Application runs without any error. I don’t know whether db has created or not. But console message shows that db created successfully. I can’t see created db in browser console.
Whenever i tried to retrieve data’s from db. It returns {object Object}.

I have posted my code in Github repository. Please anyone suggest idea why my code doesn’t work.

My ionic info:
global packages:

@ionic/cli-utils : 1.5.0
Cordova CLI      : 7.0.1
Ionic CLI        : 3.5.0

local packages:

@ionic/app-scripts : 2.1.3
Cordova Platforms  : android 6.2.3
Ionic Framework    : ionic-angular 3.6.0


Node       : v6.11.1
OS         : Windows 8.1
Xcode      : not installed
ios-deploy : not installed
ios-sim    : not installed
npm        : 3.10.10

Thanks in Advance
