I think you are quite confused :) Use procedures, not macros. If you
really want to use s-expressions, use alists and define accessor
procedures, and be sure not to mutate literal values. You could use hash
tables and records also. Or myriad other data structures. Read
http://mitpress.mit.edu/sicp/, especially the chapters on data
abstraction and state.
But above all, don't take your data structure advice from anyone who
mentions SQL :)
