What is the primary purpose of a structure diagram?

The primary purpose of a structure diagram is to model the hierarchy of processes within a system. Structure diagrams provide a visual representation of the different components of a software system and their relationships, emphasizing the organization and functionality of various processes. This helps in managing the complexity of software design by clearly delineating how various parts interact and contribute to the overall system behavior.

In software design, understanding the hierarchy of processes is crucial for ensuring that each component functions correctly within the larger context of the application. Structure diagrams serve as an essential tool for both developers and stakeholders by simplifying the representation of intricate designs into an easily understandable format.

While other options touch on relevant concepts in software development, they do not capture the specific role of structure diagrams in modeling process hierarchies. For instance, representing data in a table format or visualizing user interfaces relates more to data organization and user experience design, whereas displaying raw data focuses on data representation rather than the structural organization of processes.
