Thanks for information. But about the conclusion that Unix
is't unsuited for commercial application I think is a bit more to talk:
I think it is perfect to have this possibility to set control
on a part of a file, but I think those can't be part of operating system
while we talk about a large ussable OS. Let me said what I understood then
show me if I wrong:
A posibility to set access rights to parts of a file.
I.e some user should be allowed to read from offset n*0 .. n*100,
some users to be allowed to write to offsets n*101 .. n*250 etc.
But what will happend if other database engine use text entrys with
variable size record? Will be forced to say: Only fixed records databases
are allowed on that OS?
Or may need an software tools wich scan for record to be read and verify
where it is second field on ther record and look for access rights.
Should be possible, but I think this tosls must be part of database
engine not on the OS kernel.
On an mainframe with a proprietary OS and wich use only one database
engine, they can implement as kernel part some security tools, but for
an OS ussable for everything ....... I think that job can't be performed
by the OS.
Did I wrong with something?
