  16 Bio::Search::DatabaseI - Interface for a database used in a sequence search
  17
  18 =head1 SYNOPSIS
  19
  20 Bio::Search::DatabaseI objects should not be instantiated since this
  21 module defines a pure interface.
  22
  23 Given an object that implements the Bio::Search::DatabaseI  interface,
  24 you can do the following things with it:
  25
  26     $name = $db->name();
  27
  28     $date = $db->date();
  29
  30     $num_letters = $db->letters();
  31
  32     $num_entries = $db->entries();
  33
  34 =head1 DESCRIPTION
  35
  36 This module defines methods for an object that provides metadata
  37 information about a database used for sequence searching.
