Hi,

I want to store matrices of the following form (but larger) in a database: 

(define m '((0 1) (1 0)))

Currently I manage to store them by turning them into strings first via:

(~a (serialize m)); Or just drop the serialize, but I figured I might benefit 
from it later.

The problem is that I can only get a string out of the database. Obviously I 
could write a parser for this, but it feels a little odd having to write one 
for such a simple, and probably common, task. 

The question I have is whether there is a common best practice for storing such 
things in a database, or whether I should write a parser? And if I should write 
a parser, I presume I should use either Parsack or Megaparsack?

Thanks,
Marc
