Hackolade Studio provides the possibility to add separate ER Diagram Views (ERDV): a subset of entities selected from the main ER diagram, to help manage large models by focusing on a smaller set of entities, by domain or subject. Entities may appear in multiple Diagram Views. Modifications made inside Diagram Views are immediately reflected in the main diagram and other views where present. And vice-versa.
