A method and system for searching, filtering, creating, displaying, and managing entity relationships from a repository of data hierarchies through a user interface is provided. Relationships of a primary entity and its related secondary entities are retrieved and displayed in a unified view in graphical or text view. The unified view may indicate a “cross” relationship between first and second entities through another entity that connects the first and second entities, the first and second entities originating from different data hierarchies and/or data sources. Relationships of a selected secondary entity may be displayed in a unified view and entities or relationships may be updated or stored to a separate storage area. The method and system may be used within an enterprise for implementing Master Data Management or Customer Data Integration for managing data hierarchies containing customer information, human capital information, supplier information, asset information, product information, or financial information.
