Point of Sale System Deployment Diagram Description

The point-of-sale system allows companies and other profiting establishments to collect customer payments and keep track of sales. It looks simple, but depending on whether you sell online, have a storefront, or both, the setup can be complicated.

A point of sale (also known as a point of purchase) is where customers are billed. When customers check out online, come up to your counter, or pick something up from your stand or booth, they are at the point of sale. The equipment and software that allows your company to make such sales are known as your point-of-sale system.

UML Deployment Diagram for Point of Sales System

A deployment diagram for the point of sale (POS) system in UML is used to illustrate its’ physical architecture. In UML, deployment diagrams can show you how the software and hardware of the learning system work together and where the processing takes place.

The POS system uses a UML deployment diagram to show how should the developed software be deployed. It clarifies the communications between links(nodes) which helps the project to work according to the design given to it. Deployment diagrams depict the setup of run-time processing nodes and the components that reside on them.

Deployment Diagram for Point of Sale System

The designed deployment diagram for POS system shows the components (nodes) included to carry out the process. Nodes are represented by boxes that are labeled as software or hardware that specifies the included components to carry out the point of sale process. The boxes will then be connected and labeled to declare the type of connection they have with the other components.

With a point-of-sale (POS) system, your company can receive payments from customers and track sales. It sounds straightforward, but the arrangement can work in a variety of ways depending on whether you sell online, have a physical storefront, or both.

Point of Sale System UML Deployment Diagram (Explanation)

The Point of Sale System UML deployment diagram explains the sketch of the relationship between software and hardware. These hardware and software are labeled to clarify their part in the system’s operation. They were represented by nodes and the connections were represented by labeled arrows.

The deployment diagram shows the scenario when the system is deployed. It has 4 nodes represented with boxes and relationship connections. The nodes are the workstation (point of sale system), the system server, the barcode scanner, and the receipt printer. The system server node contains a developed database that will hold the details of the system.

For the connection, the system is connected to the server database using a database connector which enables it to pass a connection to the devices and enable users to access the system’s database.

Advantages of POS System Deployment Diagram

  • Portrays the deployment view of the POS system.
  • Helps in visualizing the topological view of the point of sale system.
  • Models the physical architecture of the POS system.
  • Shows the relationships between the software and hardware components in the point of sale system.
  • Shows the physical distribution of the system’s processing.

Steps in Developing Point of Sale System Deployment Diagram

Time needed: 10 minutes

Here are the steps in developing the point of sale system deployment diagram.

  1. Determine the diagram’s purpose.

    To determine the purpose of the deployment diagram, know the description of the POs system. The purpose of the deployment diagram is to design the needed components (software and hardware) of the system. This is to support and imply the whole processes when the point of sale system operates.

  2. Add the diagram’s nodes.

    The term “node” refers to the physical devices that make up the system. Artifacts are deployed on these nodes. Node instances on which artifact instances will be implemented are also possible.

    The essential software or hardware elements, or nodes, in the system are represented by the three-dimensional boxes known as nodes. The smaller forms included within the boxes reflect the software artifacts that are distributed, and the lines from node to node indicate relationships.

  3. Add more pieces to the diagram, such as components or artifacts, if needed.

    A deployment diagram depicts the locations of components and artifacts in the deployed system. In a software system, artifacts are model elements that reflect physical entities. Executable files, libraries, software components, documents, and databases are examples of physical implementation units.

  4. Add communication associations.

    A communication association (path) is a sort of relationship between nodes in a deployment diagram that indicates how they communicate messages and signals in UML modeling. Deploy relationships in UML show that a certain type of node can be used to deploy a certain type of artifact.

    A message or other sort of communication between nodes is indicated by a line called a relation or association.

Additional Knowledge

The topology of the physical components of a system, where the software components are installed, is visualized using deployment diagrams. Deployment diagrams are used to depict a system’s static deployment view. Nodes and their relationships are depicted in deployment diagrams.

The Deployment Model shows how components will be distributed across the system architecture in detail. It contains information about network capabilities, server specifications, hardware requirements, and other aspects of the planned system’s deployment.


You need to know the diagrams used to design and develop the point of sale system. That is because you cannot perfectly create a fully-functional system without it. But if you create this deployment diagram, you will know the software and hardware components that the project should possess. Not only that, you will find out the needed specifications and connect them to the other UML Diagrams.

The deployment diagram is used to model the system’s physical architecture. It describes the connections of components between software and hardware system. By completing the Diagrams per module or per process, you will easily achieve your desired system. Check out our Related and Recommended Articles for more Learning and Information.
