[GNC] Delete, copy and paste to fix mistakes?

A caveat about this. Any method of storing data could be used by 
multiple people, as long as they have access/permissions to the data. 
However, this is one person at a time. Simultaneous changing of the data 
is not allowed. I believe it's a case of "whoever saves last wins". The 
program reads the data from the database when you open the file only. 
All work you do is only affecting the data in your computer's' memory. 
The data in the database is only updated when you execute a save 
operation in the program.
