Detailed explanation-1: -A structure chart is a top-down modular design tool, constructed of squares representing the different modules in the system, and lines that connect them. The lines represent the connection and or ownership between activities and subactivities as they are used in organization charts.

Detailed explanation-2: -Structure charts employ two main graphical elements: modules and arrows. The structure chart shapes that are modules typically appear as labeled rectangles, and the arrows denote relationships between the modules, such as direction of data movement.

Detailed explanation-3: -A hierarchy chart is a picture showing the relationship of modules within a problem solution. Each module is represented as a box containing the module name. Each module which has been decomposed into simpler modular activities, is drawn with those sub-module activities under it and connected to it.

Detailed explanation-4: -Structure Charts. Structure charts are intended to give visual representations of the logical processes identified within the design. There are some variations to the exact notation used in structure charts, but all include an inverted tree structure with boxes showing each of the main logical actions.
