What does Gane-Sarson notation represent in system analysis?

Gane-Sarson notation is specifically a type of data flow diagram (DFD) notation used in system analysis and design. This notation provides a way to visualize the flow of data within a system by depicting how data is input, processed, stored, and output. The Gane-Sarson diagrams allow analysts to represent connections among different processes and data stores clearly, facilitating a comprehensive understanding of how data moves through a system.

In contrast, while defining system requirements is an essential aspect of system analysis, Gane-Sarson notation does not directly serve as a method for requirements definition. Instead, it translates those requirements into a graphical format that highlights data flows. It’s also important to note that Gane-Sarson notation is not a coding language or a quality assurance method; those concepts serve different functional purposes in the development and maintenance of systems.

Thus, the identification of Gane-Sarson notation as a type of data flow diagram notation is accurate because it emphasizes its role in visually representing data processes, making it easier for stakeholders to comprehend the system’s functions.
