I apologize if this post is 'out of order'. If so, the moderators should feel free to delete it.
I am sure that my recent questions have shown my incompetence with ObjectDB (although I have used many other SQL and non-SQL databases). Therefore, my questions must seem trivial.
So often one sees condescending answers to beginners like "why don't you read a book first", "you should take a course", "why don't you search the forum first" and so on. In this forum, I feel that my questions are taken seriously and answered meaningfully, in a respectful tone, and certainly very prompt.
This forum should be highly commended for that. It reflects positively on the ObjectDB itself. Great thanks to support!
