In the context of a Configuration Management Database (CMDB), a cascade relationship typically refers to a type of relationship between configuration items (CIs) or configuration items and other entities in the CMDB.
A CMDB is a database used in IT Service Management (ITSM) and ITIL (Information Technology Infrastructure Library) practices to store information about various components of an organization's IT infrastructure, such as servers, software, network devices, and their interdependencies. Relationships between these CIs are crucial for understanding the impact of changes and incidents within the IT environment.
A cascade relationship implies that when a change is made to a parent CI, it has a cascading effect on one or more child CIs. This means that any updates, modifications, or changes made to the parent CI will automatically be reflected in the child CIs, ensuring that the information in the CMDB remains consistent and up-to-date.
