Project file created by Visual Paradigm for UML, a diagramming application included in the Visual Paradigm Suite; can save multiple kinds of diagrams for a single project, including UML diagrams, business process diagrams, entity relationship diagrams, and others. VPP projects are generally used for documentation during the concept and planning phases. Each diagram saves drawn objects and connectors that can represent a variety of objects and flows for a business process or software design. By documenting these concepts before implementation, developers save time and money and reduce the risk of unplanned issues arising in the latter project stages.
