1:n |
- A configuration item that belongs to the source classification can have the relationship with multiple configuration items that belong to the target classification.
- A configuration item that belongs to the target classification can have the relationship with only one configuration item that belongs to the source classification.
- For example, you specify a 1:n cardinality for an installed with relationship between computer systems and operating systems. Therefore, a computer system instance can be installed with many operating system instances. This 1:n value also implies that an operating system instance can have an installed with relationship with only one computer system instance.

1:1 |
- A configuration item that belongs to the source classification can have the relationship with only one configuration item that belongs to the target classification.
- A configuration item that belongs to the target classification can have the relationship with only one configuration item that belongs to the source classification.
- For example, you specify a 1:1 cardinality for a runs on relationship between operating systems and computer systems. Therefore, an operating system instance can run on only one computer system instance.

n:1 |
- Multiple configuration items that belong to the source classification can have the relationship with only one configuration item that belongs to the target classification.
- A configuration item that belongs to the target classification can have the relationship with multiple configuration items that belong to the source classification.
- For example, you specify an n:1 cardinality for an installed on relationship between operating systems and computer systems. Therefore, multiple operating system instances can be installed on one computer system instance. This n:1 value also implies that an operating system instance can be installed on only one computer system instance.
