A structure diagram is a conceptual modeling tool used to document the different structures that make up a system such as a database or an application. It shows the hierarchy or structure of the different components or modules of the system and shows how they connect and interact with each other.
It is a tool used to guide developers to ensure that all parts of the system work as intended in relation to all the other parts. Techopedia Explains Structure Diagram A structure diagram is a development tool used in modeling the different parts of a system, from the overview on how the individual parts interact to create the whole, to modeling the details of the smallest parts themselves such as the different objects and classes being used in programming the system.
A structure diagram visualizes how a system works from the initial input, to processing and, finally, to the desired output. It is especially useful in determining all of the interfaces involved between the different parts and helps developers agree on how each part should be connected based on the models being shown on the structure diagram. But if you are working on a large project or process, then you need to use flow chart because it is not a one-day job and you might forget the steps of programming you were working on, which leads to confusion or errors.
Creating Program structure diagram also helps to understand the process easily later in the future when someone else would be working on it. Edraw contains special shapes and settings for creating program structure diagrams.
Various program structure symbols or boxes are used to create a program structure diagram depending upon the requirements and processes. Some processes are small and do not require connectors while some need various types of connectors to handle many conditions. With the advent of new technologies in the field of flow chart creation, it has become an easy task. I would always suggest you to use program structure to ease the process of understanding the system and its flow.
The following are some program flowchart templates in Edraw Flowchart Software. Structural Diagram Brief Description Composite Structure Diagram It shows the internal structure of a classifier, classifier interactions with the environment through ports, or behavior of a collaboration. Deployment Diagram It shows a set of nodes and their relationships that illustrates the static deployment view of an architecture. Profile Diagram Class Diagram It shows a set of classes, interfaces, and collaborations and their relationships, typically, found in modeling object-oriented systems.
Object Diagram It shows a set of objects and their relationships, which is the static snapshots of instances of the things found in class diagrams. Component Diagram It shows a set of components and their relationships that illustrates the static implementation view of a system.

It is a graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. It shows the discrete behavior of a part of a designed system through finite state transitions.
It shows the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. It depicts a control flow with nodes that can contain other interaction diagrams. It shows interactions when the primary purpose of the diagram is to reason about time by focusing on conditions changing within and among lifelines along a linear time axis. It shows the internal structure of a classifier, classifier interactions with the environment through ports, or behavior of a collaboration.
It shows a set of nodes and their relationships that illustrates the static deployment view of an architecture.
