inverse attribute in hibernate
Hi,
I would like to know when we use inverse attribute. I saw setting inverse=true within set property attribute while doing many-one, one-many association hibernate examples. any ideas, suggestions, sample code, resources, links highly appreciated.thanks in advance

>>>In a one-to-many association it has to be the many-side, and in many-to-many association you can select either side
I have not clearly understood this. Can you please elaborate this.

What is “inverse”?
This is the most confusing keyword in Hibernate, at least i took quite a long time to understand what is it. The “inverse” keyword is always declared in one-to-many and many-to-many relationship (many-to-one doesn’t has inverse keyword), It defines which side is responsible to take care of the relationship.
Always put inverse=”true” in your collection variable?
There are many Hibernate articles try to explain the “inverse” with many Hibernate “official” jargon, which is very hard to understand (at least to me). In few articles, they even suggested that just forget about what is “inverse”, and always put the inverse=”true” in the collection variable. This statement is always true – “put inverse=true in collection variable”, but do not blindfold on it, try to understand the reason behind is essential to optimal your Hibernate performance.
“inverse”, can it change to “relationship owner”?
i still not clear on it. please advise
