I am trying to figure out the best way to do this and granted I am not sure my
architecture is the most sane or sensible way to handle it. I am trying to
build my DB interface and I want to allow the system to deal with numerous
types of data stores. So I have a config file that is read and gets the
information needed. So to pseudo lay it out:
(define (query-db where-clause))
(define (db-type)
(cond
[(=? db-conf '(mysql)) (????)]) ;something to redefine how query-db
actually works.
)
Maybe this is silly as in query-db I can just do a conditional for each type.
But then I have to do a conditional for each DB action, connect, drop, query,
update, etc. I was thinking loading the conditional and redefining place
holders would be a more elegant solution. I don't know just spit balling with
a different design pattern here.
