Link table structure

Dear forum,

I have a database in which each table has to be present in eleven
copies for back-ups/second data entry. Making a change to a table
therefore appears to require copying and pasting over each of the ten
back-ups, unless there's some way to link the table structure or
otherwise simultaneously change the structure across multiple tables.
Does anyone have any suggestions that might help with this? Best
regards,

Patrick
