Refactory Entity Relationshp

Hi!, I did reverse engineering from a very big database. VP has put the Entities (tables) in the root of the model tree view.

I am thinking refactory Entity Relationship diagram creating a more abstract view presenting Package and Relations then each package will have an Entity Relationship diagram with the package detail.

Is correct to create the abstract view (composed of package only) using “Package Model” with <> stereotype?

What is the definition of <> and <> stereotypes?

thanks in advance
