Thank you. If you have ready simplest example it may be useful for
review.
My strategy is to minimize number of packages used as dependencies so
I try to use what is built in or to re-use what is inside of Emacs.
For simplest database with hundreds of entries file locking and Lisp
data can be enough.
For larger database I would prefer GDBM bindings built-in, but life is
not a dream.
Personally I am using PostgreSQL. Then I just define the table
definition and that may be similar to eieio.
