Yes indeed, that's the genetic lack of open systems, but i wanted to especially point that because in only one operation you can make a lot of desagrements in many tables ; multiples accesses to each dbf to modify them needs a longer time and maybe is easier to trace back. > Normally a "$ Share is sufficient to hide the data away from potential > prying eyes on server hosted hardware.

You know, my mind is always wondering when i see asks and further discussions about that problem ; because it is not new, and through dozens of years still the same old chats are remaining, as algorithmic solutions have been found long time ago. So, sometimes it becomes boring. So that, so what ? It looks like a psychotic fix about this point, but what about the multi-user update of a "normal" value, like a stock value ? That is the same game. In earlier 70's, when neither RDBS nor L4G existed, we had, using procedural languages (as COBOL) to respond to the same questions. And we did it. It is curious that this knowlegde basis can't be transmitted trough generations of valorous programmers ... > The only really secure way of hiding your data is not to put it in DBF's > in the first place but to put it into a SQL container like M$SQL or > > MySQL etc. IMO, the only really secure way is to fully understand the underlying mechanisms, and practise, practise ... MSSQL is not written in MSSQL language, nor MySql is written in MySql language. They are written in low-level language, the same ones that we used long ago. Presentation and application layers have obscured minds.
