What is a part property?

A part property is defined as an internal structural element of a block. In the context of systems modeling, particularly within the Object Management Group's modeling standards, it refers to components or subdivisions of a block that define its internal structure. Part properties are used to represent the relationships between different elements within a system, indicating that a block contains other blocks or values. This allows for a hierarchical representation of system components, making it easier to analyze their interrelations and functionalities.

Understanding part properties is crucial in the context of building complex models, as they help clarify how various elements work together within the overall architecture of the system. This internal structure aids in delineating responsibilities and behaviors among the parts of a block. Thus, recognizing part properties as internal structural elements is essential for effective modeling in system design.
