Naming SQLAlchemy models vs Pydantic models

Hi all, how do you generally deal with naming conventions between Pydantic and SQLAlchemy models? For example you have some object like Book. You can receive this from the user to create, or it might exist in your database. Do you differentiate these with e.g. BookSchema and DbBook? Some other prefix/suffix? Is there a convention that you've seen in some book or blog post that you like?
