The question is rather simple. I know that there is SQLite. There is Core Data also. But I need something in between. More object-oriented than SQLite API and simplier than Core Data.

Main points are:

• I need access to stored entities only by id. No queries required.
• I need to store items of a single type, it means that I can use only one table if I choose SQLite.
• I want automatic object-relational conversion. Or object-storage if the storage is not relational.

I can use object archiving, but I have to implement things (NSArchiver).

But I want to write some kind of class and get persistence automatically. As it can be done with Hibernate/ActiveRecord/Core Data/etc.

Thanks.
