Can we add comments or a README file to a SQL Server database/table?

These days I am importing quite a lot of databases from my server and working on them locally. In 开发者_如何学Gothe process, I am making a number of changes to the table structure and in the process using some complex SQL statements to add the table columns.

Keeping track of everything in a separate file is beginning to be a pain and am wondering if there is a way to do this directly in the SSMS so that I can store the instructions along with the database. Is there any way this can be done or do I have to resort to writing documentation outside SQL Server?

Of course, I can always create a stub table called comments and put everything there but I was looking for a way to associate comments with a particular database or tables. Any suggestions would be greatly appreciated.

SQL-Server handles commenting on database objects through Extended Properties:
