1. In modeling: The minimum and maximum number of ↑objects in a relationship.
   
2. In mathematics: The number of elements in a set.

A representation of a set of ↑objects of the same kind by describing the structure of the objects, the ways they can be manipulated and how they behave.

A diagrammatic representation of a ↑class model.

A model consisting of a set of ↑classes and relationships between them.

1. In general: A delimitable part of a ↑system .
   
2. In software architecture: An encapsulated set of coherent ↑objects or ↑classes that jointly achieve some purpose.
   
3. In testing: A part of a ↑system that can be tested in isolation.

1. An ↑item that is composed of a set of items; forming a whole-part relationship.
   
2. The act of composing a whole from a set of parts.

The degree to which a set of ↑requirements is free of contradicting statements.

1. In general: The network of thoughts and meanings needed for understanding phenomena or utterances.
   
2. Especially in RE: The part of a ↑system's environment being relevant for understanding the system and its ↑requirements.

1. A diagrammatic representation of a ↑context model.
   
2. In ↑Structured Analysis, the context diagram is the root of the ↑data flow diagram hierarchy.

The boundary between the ↑context of a ↑system and those parts of the ↑application domain that are irrelevant for the ↑system and its ↑requirements.

A ↑model describing a ↑system in its ↑context .

The degree to which the information contained in a ↑work product is provably true.

A person or organization who receives a ↑system , a ↑product or a ↑service . Also see ↑stakeholder .
