how do you change a database design to Top-Down?

Question by Chardy: how do you change a database design to Top-Down?

I’m sorry for asking such a stupid question, but I’ve never done this before.
I’m talking about EDITING a database, not making a new one.

In general, you can’t. A database “design” is its schema, and if the schema is wrong, you need to start over with a better schema. But once that is done, you can usually convert the old data over to the new schema.
