You should denfinitely read
"Entreprise JavaBeans" by Tom Valesky, published by Addison-Wesley... In the mean time :
(from the book)
Read_uncommitted : permits dirty reads, non repeatable reads and phantom reads;
read_committed : permits only nonrepeatable reads and phantom reads;
repeatable_read : permits only phantom reads
serializable : permits none of those situations
