title: How to edit an existing and working Schema in MySQL Workbench?
body: <p>Is it possible to continue or extend an existing schema with MySQL Workbench?
  This is the scenery:
  1) We design our DB in MySQL Workbench
  2) We export it as SQL file and execute it in our MySQL Server
  3) We insert a lot of data and use our DB
  4) We want to add more tables, fields, or anything to our Schema</p>
  
  <p>The 4 step is my dude, can we edit our scheme in MySQL Workbench if our DB is working and with data?</p>
