The two main objects found in the Configuration Management Database (CMDB) are indeed cmdb_ci and cmdb_rel_ci.

The cmdb_ci object, which stands for "Configuration Item," captures all the individual components in your IT environment that are under configuration management. This can include hardware, software, documentation, and any other CIs that are crucial for managing IT services. Each cmdb_ci entry contains attributes that describe that particular configuration item, such as its type, status, and any related service dependencies.

The cmdb_rel_ci object, representing "Configuration Item Relationships," is used to define and manage the relationships between different configuration items. This is vital because understanding how various CIs interact and depend on one another helps organizations to identify potential impacts of changes or failures within the IT infrastructure.

Together, cmdb_ci and cmdb_rel_ci form the backbone of the CMDB by not only storing data about the components themselves but also their relationships, thereby enhancing visibility into the IT environment and facilitating better decision-making and service management.
