@KVD. There is a free version of SQL Server. It is called SQL Server Express. You can actually deploy a small production database with Access and SQL Express--with licensing only for the developers' copy of Access. The backend is free of licensing costs. You can deploy the Runtime version of Access for all users.
That said, I'm not sure I'd want to make SSE the default backend for Access, but it ought to be relatively straightforward to make it an alternative for those who want it.
I'm not going to vote for this one as other suggestions seem to warrant more attention (IMO). But cost just isn't an issue here.
Interesting idea. Although many developers use comments in code, and a table of changes, it would be very convenient to have that functionality at the push of a button.
Spreading rumors of this sort is not helpful to anyone, Mr. Ruperto.
Besides, if someone "...who recently attended the MVP Summit..." made such a statement, it would most likely be a violation of NDA we all sign prior to the event. On that basis alone, I have to suspect this one is made up out of whole cloth.
Alan has explained this quite well, but it doesn't hurt to add a bit of support.
All you need to do is edit the file name! And all a user has to do to recover the full content of the file is to put the "b" back in place of the "r".
There's no security involved. It's all about the runtime EXPERIENCE.
