Where to find the relationship between parent and child BOL objects for custom Component

Hi all,

             I would like to know where exactly I can find the relationship between parent BOL object and child BOL object. In our project, they developed custom component and Component set. They have defined two custom BOL Objects. They created custom Zenil class. My question is I checked in SPRO( both Simple Object and Genil Interaction) but could not find Object Table, Model table except Implementation class. I only see the implementation class defined for the Component( which is related to the Component Set) in SPRO( Basicfunction-> Genil Interaction Layer).

Can anyone explain where the relationship between the parent and child object is established? I am able to see the root object(parent) and dependent object(child) and relation between them in GENIL_MODEL_BROWSER.

Help in this regard is really appreciated.

Thanks,

Baasanthi.
