I use maps a lot for inserts and queries since I'm working with a database 
and data model that are pretty disparate; as a result, when I do inserts, I 
need to provide additional data that's not a part of my POJO.  For example,

my.pojo.Entity {
  Long entityId;
  Set addresses;
my.pojo.Address {
  Long addressId;

Address table in DB:

So when I do an address insert, I end up putting all the address info in a 
map along with the entityId.  Maybe there's a better way...  I don't use 
maps for results sets because I can usually join the tables well enough to 
get all the data I need to populate my POJOs.
