dselect was developed at around the same time as dpkg and by the same
person. It uses dpkg's database; in fact its author has occasionally
said to me that it's possibly a little too intimately connected with
dpkg, in that /var/lib/dpkg/status is partly the current state of your
system and partly what dselect wants to do with it.

apt was developed several years later and uses its own database for a
number of reasons, some feature-related, some performance-related, and
some political.
