Under which topic it will come? I am confused, please tell me.

Chain allows users to share information about work done with rough sleepers and about their needs, ensuring that they receive the most appropriate support and that efforts are not duplicated.

For a tree there will be a parent child relationship.

For a relational there will be some logical query statements.

For a network there will be logical communication like router-router.

But for chain there will not be any logical relationship, because the nodes are connected in circular manner.
