Structure Chart
•A structure chart represents the software architecture, i.e. the
various modules making up the system, the dependency (which
module calls which other modules), and the parameters that are
passed among the different modules.
•Since the main focus in a structure chart representation is on the
module structure of the software and the interactions among different
modules.
•Structure chart is a chart derived from Data Flow Diagram. It
represents the system in more detail than DFD. It breaks down the
entire system into lowest functional modules, describes functions
and sub-functions of each module of the system to a greater detail
than DFD.
•Structure chart represents hierarchical structure of modules. At each
layer a specific task is performed.
