The Code Road Map is a model of the application code; it displays two different levels: code only and code plus data. Use the Road map to view PL/SQL interdependencies within a database.
Code Only - a graphical representation of the run-time, call-stack dependencies. There are three additional options for this mode:
expand packages for calls into them
include calls to SYS owned PL/SQL
include calls to other schema’s PL/SQL
Code Plus Data - what database objects the code references and in what manner (for example, read versus write). You can also include:
pertinent triggers
pertinent views
Note: Views are essentially treated as tables.
