How to visualize relation between objects in a database? <p>I have a database which I want to visualize in some kind of tool. Let me explain the basic: Company A does business with Transport Company A and Transport Company B. Transport Company A does business with Company A, Company B and Company C. Company C does business with Transport Company A and Transport Company B. </p> <p>As you can see every Company does business with different Transport Companies and vice versa. These relationships can be implemented in a database, and when drawing a visual model on paper this is also very easy. </p> <p>Of course the model should contain hundreds of Companies and Transport Companies. So I want to have a visualizing tool, <strong>where a overview of these relations can be displayed.</strong> </p> <p>My question is which tools can be used for realizing this?</p>
