The simplest relational database format?

Question

Database

Is there some simplest (basic) relational database format,
data from which is easily parsed / transferred to any other "more sophisticated" database.
Something like the parent of all relationals.

I am also interested in the presence of a simple program to create and edit such a file manually.

It is necessary for any small experiments.
Found the DBF format. This is it?

Answer 1

CSV, XML are usually supported for import in many DBMS.

Answer 2

I would look towards sqlite (along with some manager). You can play around with SQL queries, and export-import is much easier to set up than with DBF.

Answer 3

data from which is easily parsed / transferred to any other "more sophisticated" database.

All this is done not through format parsing, but through SQL, and in case of incompatibility, either a converter is used, or a transfer script is written in any available PL.
