Solution 1

"Relational databases" refer to the fact that you define relations between table structures which decompose your data into logical groups and recombine them again for queries.

"Non relational databases" do not define relations between groups of "tables".

So the answer is yes you can do non relational things while using the "relational engines" of existing database engines for storage.

Well, no. Non-relational data bases are not relational databases with removed relations :-)
They are the databases based on different models. For example, hierarchical model allows only a very limited subset of relations compared to relational model -- only those composing a tree. Other models allows only associative collection of data. And so on... The question just makes no sense, that's it. (I did not vote this time.)

HeHe! You can implement anything in files hence you can use access as a file, granted the data model you will have to handle yourself.

Ask a silly question, get someone in trouble answering it :)
Cheers Sergey!

I think that needs some proof, which can be done only for some particular, fully described database model. For example, its absolutely clear that a hierarchical database can be implemented on top of relational. For all others -- who knows what it is? Such questions should never be considered. The proper answer, for example, would be -- explain to me the database model, and I'll try to answer this question.

The problem is: the notion "non-relational database" is not something certain.

--SA; my question makes no sence? thank you, your answer is same as well!!! u could explain the database model ayway, but clearly u r not a good teacher... Besides, no body prompts u to answer when the question does not like your majesty!

Mehdi; thank u what ever the answer was correct or wrong...
