Subject Database protection
Author Johan van Zyl
From Clarion NG
Hi Charles,

So, basically my SQL research from long ago may actually be correct, or I am
now very confused with regards to what Bernard said.<g>

If you are correct, then basically there is no real database protection when
one chooses to use an SQL backend for a commercially sold product. Any dba
or consultant could easily accomplish the goal of gaining access to any SQL
db without the need for permission from the original dev. Your comment#2
suggests that this is really a trivial thing to accomplish.

I certainly agree with your comment#3... I'm not looking to lock a user out
of their own SQL Server totally (just when it comes to my apps).
I simply wanted to know if SQL backends provided a secure means of blocking
all users (dba's, consultants, end-users, etc.) from conjuring up a way to
gain access to the database (assuming the user had full access to the server
which held the database).
IMO, this is what a TPS file brings to the table. Nobody can read a single
file without contacting me, the developer. I remember a few years ago, I
had a smart cookie try to gain access by purchasing the ODBC from TS. They
found out later that they still needed the password.<seg>


Can someone confirm that Charles statement is in fact true?
It certainly corroborates my initial findings some years back.

I am simply trying to confirm whether or not a secondary password or method
now exists that truly locks all dba's and wannabe consultants from TOTALLY
prying into an SQL database without the use of my application?


I seem to have conflicting information on this matter.
Either way I'm going to go SQL in my future projects, but I want to know
what I'm up against.<g>

Later,
Doug
