Update Database


Sorry for this newbie question, but just started using Data Modeler today. Have a SQLite project and adding a new field to one of the Tables. Everything looks fine in the Data Modeler, but using a different tool I don't see the database changes outside the Data Modeler. 
How to actually update the database with the changes done in Data Modeler?
Thanks in advance,

Data Modeler doesn't update the database automatically. It generates a SQL script for creating (or updating) the database, but it's up to you to execute the script in the database. Also, the Data Modeler is not associated with any database. Although you can import a database structure into a project, it doesn't save the association between the project and the database. The project is "generic".
