Point of Sale (POS) System Project UML Diagrams
POINT OF SALE (POS) SYSTEM UML DIAGRAMS – are diagrams formed by the Unified Modeling Languages that acts as the blueprint for the project development. It shows the needed diagrams based in UML to guide you in building your Point of Sale (POS) System. These UML Diagrams is composed of Use Cases, Activity Diagrams, Class, Sequences and many more.
Here’s how to get you started. Let us discuss why an Point of Sale (POS) system should have these UML Diagrams, What are UML Diagrams, How to form them and how they actually work. In this article you will also know the bonus diagrams that will help you in understanding how the Point of Sale (POS) System works. Each of these UML Diagrams comes with complete explanation to let you understand its contribution to the Point of Sale (POS) system.
What are UML Diagrams?
UML diagram is a diagram based on the UML (Unified Modeling Language) that is used to visually describe a system, including its major actors, roles, actions, artifacts, or classes, in order to better understand, edit, maintain, or document system information.
Software engineers use the UML modeling language to create diagrams and provide ready-to-use, expressive modeling examples to users (programmers). Some UML tools create code in a programming language. The UML Diagrams are categorized into two types: the structural diagrams and the behavioral diagrams.
Is it necessary for Point of Sale (POS) System to have UML Diagrams? The answer is YES. Its because the UML diagrams are the visual designs or the blueprint of the system structure and behavior. Structural diagrams helps in building the structure of Point of Sale (POS) System while the behavioral diagrams in UML helps in determining its behavior towards the user, data inputs and producing an output. All of the UML diagrams works in sync and relatively to achieve a well-engineered project.
How to build a Point of Sale (POS) System UML Diagrams?
The first thing that you must do before building UML Diagrams for the System is to collect as much Point of Sale (POS) data as you can. You’ll need to know how they manage sales information, processing transactions and distribution of products. You must complete all the necessary information in order to provide a quality system for them. Then you’ll apply the data gathered in designing the UML diagrams.
The purpose of building the system is to provide the company crews and owners the easier and efficient way of doing their tasks. And in order to do that, you have to complete the needed diagrams to perfectly furnish your project. Build your project completely using UML Diagrams to help you and keep you from repeating its development.
Point of Sale (POS) System Project UML Diagrams:
Time needed: 15 minutes.
Here are the UML Diagrams that composes a Point of Sale (POS) System. Each of the UML Diagrams has a major role in achieving a well-developed and functional Point of Sale (POS) System.
- Point of Sale (POS) Class Diagram
The Class diagram for Pont of Sale (POS) System shows the structures of information or data that will be handled in the system. These data or information will be represented by classes. Each of the classes will have their attributes in accord to the methods they will use. So the UML Class diagram was illustrated by a box with 3 partitions and the upper part was the name of the class, the middles are the attributes and the bottom is for the methods. The arrows on them represents their relationships in each other.
So the classes that must be made in a Point of Sales (POS) System are the admin, customers, sales, sales clerk, product and transactions or reports. The mentioned classes were just general. If you want more complex or wider scope of Point of Sale (POS) System, then you can add your desired classes.
- POS (Point of Sale) System Use Case Diagram
The use cases in the diagram represents the main processes in Point of Sale (POS) System. Then they will be broken down into more specific use cases depending on the included processes of the main use case. Each of these use cases explains how the system handles the actions or scenarios requested by the user.
The UML Use Case Diagram is a design used as one of the Methodology on Point of Sale (POS) System development. It represents the main functions or processes of the system as well as the specific processes included. They were also labelled properly to guide programmers and users about the structure of Point of Sale (POS) System.
- Point of Sale (POS) System Sequence Diagram
The designed sequence diagram illustrates the series of events that occurs in Point of Sale (POS) System. In this illustration, the actors are represented by a stick man and the transactions or classes are represented by objects. It will give you clear explanation about the behavior of an Point of Sale (POS) System in terms of processing the flow of instructions.
This designed sequence diagram is able to show programmers and readers about the sequence of messages between the actor and the objects.
- POS (Point of Sale) Activity Diagram
Here’s the UML activity diagram design of Point of Sale (POS) System that you can use for your own Final year Project. The UML activity Diagram is used to show the interaction of the user and the system. By creating it, you’ll be able to see the flaws of the system and you may avoid it once you apply it to the project development. So it is important to have your diagrams designed first before jumping into its development.
Now to create this kind of diagram, you have to determine the processes involve, the users and finalize the behavior of your proposed system.
Bonus Diagrams for Point of Sale (POS) System
- Point of Sales and Inventory System Database Design
This diagram shows the design of the system’s database. This design could be applied at the back end of the system development. It also serves as the design for the data storage that the system needs. It secures all the essential data in the system and preserves them for important task or when needed.
- POS (Point of Sales) System DFD
As addition to the diagrams that will be a big help in doing your Project is the Dataflow Diagram. It does not belong to the UML diagrams but it also helps in knowing more about the Point of Sale (POS) System. So the DFD serves as an illustration of the systems data handling. As you can see, this DFD design is in level 2, it has levels 0,1 and 2 but the most complex and wider among the 3 is the level 2. So here you will see the main processes included. You may relate these processes from your use case Diagram.

To design your UML diagram, you may use platforms and editing tools online. These tools are helpful since they already have the needed symbols to illustrate your diagrams. You just have to plot the included symbols, arrows and labels. The platforms or online tools that you may use are:
As a whole, the UML Diagrams works together to achieve the most desired functions of the Point of Sale (POS) System Project. All of these were designed to guide programmers and beginners about the behavior and structure of Point of Sale (POS) System.
By completing all the given Diagrams, the Point of Sale (POS) Project System development would be much easier and attainable. So those UML diagrams were given to teach you and guide you through your project development journey. You can use all of the given UML diagrams as your reference, or have them for your project development. The ideas presented in UML Diagrams were all based on Point of Sale (POS) System requirements.
