# Configuration Management Database A configuration management database (CMDB) records configuration items and the relationships needed to operate and recover systems. The notebook anticipates a personal CMDB by mapping model, serial, MAC, IMEI/EID/ICCID, power supply, account suffix, person, project, and location on paper. ## Archive use The canonical asset graph should add acquisition date, owner/custodian, lifecycle state, firmware/OS, encryption, backup coverage, service history, source evidence, confidence, and disposal status while keeping credentials in a separate secure system. ## Relationships [[Asset Management]] · [[Digital Continuity]] · [[Identity Continuity]] · [[Credential Security]] ## Scanned_20260730-1958 overlay [[Scanned_20260730-1958]] broadens the paper CMDB from unit identifiers into relationships among accounts, domains, registrars, cloud providers, devices, management state, contacts, and physical locations. The notebook’s useful object is the edge as much as the node: which mailbox recovers which platform, which domain controls which mail, and which device carries which authenticator. This is the archive’s clearest analog precursor to an [[Identity Dependency Graph]]. Its main weakness is that credentials and inventory share the same physical trust domain.
