In the ServiceNow Configuration Management Database (CMDB), a Dependency View is the dedicated feature used to visually represent Configuration Items (CIs) and the relationships between them.
1. Functionality of Dependency Views:
Dependency Views (formerly known as BSM Maps) dynamically generate a graphical map of your IT infrastructure. When viewing a specific CI (like a database server), the Dependency View draws a network of nodes showing what services depend on that server (upstream relationships) and what underlying hardware or software that server relies upon (downstream relationships). This visualization is critical for incident impact analysis and change management planning.
2. Why the other options are incorrect:
* A (Transform Map): This is used to map data from an Import Set table to a target ServiceNow table. It does not visualize CI relationships.
* B (Flow Design): Flow Designer is a user interface for automating business processes and building workflows, completely unrelated to CMDB visualization.
* C (Schema Map): While a Schema Map is a visualization tool, it shows the relationships between database tables (like how the Incident table extends the Task table), not the relationships between individual data records (CIs) within those tables.
Reference:
ServiceNow Configuration Management (CMDB) documentation explicitly identifies Dependency Views as the tool to view CIs and their relationships in a visual, interactive map format.
