How to set dynamic model association without foreign key cakephp3

Question

I am using cakephp 3.4.

I need to retrieve the data from two tables where no any association between them. I need to have solution where I can bind 2 models dynamically for that particular query.

There is an option to bind-unbind model, but that is an old method.

If there are 2 tables i.e. Articles and Authors without any relations/association, I could be able to find Author record while querying on Articles.
