Hi Michael,
if your concern about theft is really big, you will need
to write a second piece aof software. Translate all column
names in your scheme to col1, col2, .. and tables to tab1, tab2, ..
Of course your SQL need to be adapted. But nobody will
ever be able to make a meaning out of that. So reengineering
will be really tough. But simple copy will still work.
