Here is the description scenario:

A user has a set of described items. Those items are system predefinited and can be changed(add or delete) from time to from. A user can describe the items s/he wants. I can think of a few of implementations, but not sure which way I shall go. What is the best practice in Hiberate for this scenario in terms of domain objects and mapping.

Thanks for your inputs.

I hope I understand you well.

You say a User (you need a table named User to keep them) can have many Items (you need a table Item).

If a items can be keep by only one User, you need a one-to-many relationship between them. A user (One) can have many (to-many) Items.

Or if a Item can be under (keeps by) many Users, then you need a many-to-many relationship (you need a UserItem table).

That is some sort of idea. Later, I thought that I only need to refer the items by the object names. Those item POJOs are definited in a XML file. With this implementation, I don't need a table for the items, but still need a cross reference table. Some related issues I will consider later on.

Thanks.
