You can create domain with  you  IDE like (Domain will always create in grails-app/domain folder):

Class User 

             {

String name;

String email

String password

             }

It will create a user table in database.

The class name, by default, is mapped to the table name in lower case and separated by underscores instead of camel case so if  a domain class named UserAddress by default would map to a table named user_address . Each property maps to individual columns.
