Answer to Question 1

Dependency graphs are not a graphical display like a bar chart, but rather a set of connected nodes. The nodes represent objects such as tables, view, triggers, stored procedures, etc., in the database. Line segments show the interconnections, or dependencies, between these objects. Thus, a dependency graph is useful for determining how a change to one object in a database might affect other objects in the database.

Answer to Question 2

TRUE
