Many programming languages (including Perl, Ruby, and PHP) support hashes:
$color['apple'] = 'red';
$color['ruby'] = 'red';
$type['apple'] = 'fruit';
$type['ruby'] = 'gem';
This quickly lets me find the color or type of a given item.
In this sense, color() and type() are like mathematical funct

Without a database? I guess not. You'd still need at least SQLite.
But you are right, you could use ActiveRecord to obtain a nice object
oriented wrapper around the database so that it doesn't scare you.
Or, assuming you do

As far as languages with two-way relation go, there are many; perhaps
the most prototypical is Lisp, in that either member of a pair within
an alist can be used to look the pair up, with no extra function or
second map definition required.
But PHP has pretty good support, too, actually. If you ha

First, in the strictest mathematical sense, a relation from a set $a to a
set $b is a subset of the cross-product $a x $b.
(obviously, the mathematical notation is not a great way to represent this
in a program.)
Hence, a relation is a

Huh, didn't notice the cross-posting. But no, you're not subscribed
to any new lists.
Since we're cross-posting, the translation of my sample would be

Be careful. Next time you do it you'll be subscribed to Haskell, OCaml
and Smalltalk lists.
Bwahahaha!
