TheCMDB Builderis the primary tool used inServiceNow’s Configuration Management Database (CMDB)for creating and managingdependencies between Configuration Items(CIs). It provides agraphical interfacethat allows administrators and CMDB managers to visualize and define relationships between CIs efficiently.

Visual Representation of CI Dependencies:

CMDB Builder provides agraphical interfacethat allows users tocreate, modify, and deleterelationships between Configuration Items (CIs).

It helps in identifyingimpact analysisandservice dependenciesby mapping CIs and their relationships.

Supports Complex CI Relationships:

Allows definingparent-child,peer, anddependencyrelationships between CIs.

Helps in ensuring the accuracy ofservice mapsandIT asset relationships.

Drag-and-Drop Functionality:

Users candrag and dropCIs onto the builder canvas andconnect them using predefined relationships.

Integration with CMDB Relationship Rules:

CMDB Builder adheres toCMDB relationship rulesto ensure that onlyvalidrelationships are created.

Impact and Root Cause Analysis:

Helps introubleshooting IT incidentsby showing thedependencies between services.

Useful inchange managementto predict potentialimpactson downstream services before making changes.

Key Features of CMDB Builder:

A. CI Relationship Editor:

TheCI Relationship Editorallows users toview and edit relationshipsbetween CIs in atabular formatbutdoes not provide a graphical dependency visualizationlike CMDB Builder.

It is moremanual and less interactivecompared to CMDB Builder.

C. CI Service Manager:

CI Service Manageris used for managingCI service mappingsbut isnot primarily a tool for creating dependencies between CIs.

It is more focused ondefining service-level relationshipsrather thanbuilding CMDB dependency models.

D. CI Class Manager:

CI Class Manageris used formanaging CI classes, attributes, and extending CMDB class structures.

It is not used forcreating dependencies between configuration items.
