Hello,

I have a data model as specified in the following diagram:

What would be best mapping of classes. I have some doubts about one-to-one relationships, since usualy I put sequence id in the class that needed to be lodaed lazily.

But until now I always have had only one such property and now I need two: Miniature and Large - each of type PictureData. But where do I put a sequence id and where foreign-key?

My preferred place for sequence id is Picture class not PictureItem as I used to do before due to simplicity...

Please help me :) TIA
