And give some usages about relations would be fine!

Hi Devin, to answer your question, maybe lets start with a question: WHAT exactly is confusing you? Do you have specific questions regarding relations?

The general Type System documentation (https://help.hybris.com/6.0.0/hcd/8c755da8866910149c27ec908fc577ef.html) is not too bad to understand, so you could start there to understand Relations. But maybe there are some specific questions left open for you?!

yeah,you're right! I'm not clear about what's the usage about relations,just like search one model,etc. Thanks Rainer

Ok, understand. In this case, Arthur's answer is a very god guidance. Just do this trail and especially the pbout relations... and then you will understand, how relations work and how you handle them e.g. on code level with models.

E.g. create the "StadiumMatchRelation"...and then browse the StadiuModel class and the MatchModel class... find the methods StadiuModel.getMatches() or MatchModel.getStadium() etc..... or the related sette methods.... and just play around with these methods.

Start with the RelationTypes section of the Type System documentation. The Core training trail has step by step instructions too.
