Example of a dependency diagram, in a database that handles the affairs of a retailer

A dependency diagram is a visual representation of a dependency graph. Dependency diagrams are integral to software development, outlining the complex, interrelationships of various functional elements. Typically in a dependency diagram, arrows point from each module to other modules which they are dependent upon. Dependency diagrams are an excellent tool to simplify the database, in the process of database normalization.
