Foreign Key in UNIX File System
Hi,

Do we have Foreign Key concept in File system like UNIX, as we have in DBMS?? If yes, Can you please tell me how it is implemented in File System?

Thanks & Regards,
Archana

It does not. One file won't be a combination of the contents of several other files.

uh yes and no. There is a sort of concept of that as what makes a filesystem work. But no, this isn't an RDMS, so no real ideas of columns and rows. With that said, you could create a type of database using just a filesystem by mapping file and directories and content to database concepts.

Perhaps if you supplied more info about what you are needing, somebody here could suggest an implementation.
