Save your database diagram to update the database with the changes you made to the diagram layout and the object definitions in the diagram.
If you want to discard your changes to the diagram layout but keep the option to save your changes to your object definitions at a later time, you can save a change script. You can then run the change script at some other time to update the database. You can also edit the change script’s SQL code in a text editor before you run it.
For more information about change scripts and how to use them, see Saving a Change Script.
To save a database diagram
Database diagrams are saved in the dtproperties

table of your database.
