The Relationship Matrix is a spreadsheet display of relationships between model elements within packages. You select a source package and a target package, the relationship type and direction, and Enterprise Architect highlights all the relationships between source and target elements by highlighting a grid square.
The Relationship Matrix is a convenient method of visualizing relationships quickly and definitively. It also enables you to create, modify and delete relationships between elements with a single mouse click - another quick way to set up complex sets of element relationships with a minimum of effort.
