I built a database schema (or Model?) with
This for mysql workbench version 6.0 and for exporting a schema.
Select tab MySQL Model Select File->Export->Forward Engineer SQL Create
Place a file name to be exported in the Output SQL Script File, choose your options, next
Export MySQL table Objects, filter tables
Then a file is created which you can import to your database and it creates schemas if not exists, creates tables if not exists.
In the case of models, you need to pay, many bucks, for a tool that creates schemas, tables, indexes, cascading, and all stuff associated to an existing data model.
