ORM = Object-relational mapping. Never used it. First time I was introduced to an ORM (Hibernate) my instinct said to run away. Just too much complexity involved for little gain. I usually find that my projects are well suited to key-value storage, often with a natural chronological order. In other words: A complex RDBMS table structure is not needed anyway. This again reduces the need for any ORM.
