Same Data appearing for multiple users

I have created and android application in Dropsource and using backendless as database managment. the data which is created by one user is reflecting/ appearing for all the different new users. How can i solve this problem.

My requirement is if a new user registered and open the application there should be empty lists display until he creates a new one and save it.

Hello @Harish_Kotapati

If you want to separate data for each user you should create user relation in your data table. So each data object reference the user it belongs to.
And when user opens the application you should retrieve the data that is related to this user.
For more information please visit documentation
