Online Shopping Cart UML Diagram | UML Diagrams

The Online Shopping Cart UML diagrams are based on Unified Modeling Language which was used to represent the system’s primary users, roles, activities, artifacts, or classes. The UML Diagrams are created to easily understand, update, maintain, and document the methodologies and development of the online shopping process.

The UML diagrams for online shopping cart were used to visualize the project. It can be done before the development begins or to document its progress once it is completed. However, these UML Diagrams can be used in any sector, not only in software engineering. Its overall objective is to help teams or developers visualize what a project is or how it will work.

What is an Online Shopping Cart?

Shopping cart software is part or equal to an e-commerce software that runs on a web server and allows visitors to an Internet site to choose things for purchase. Customers who shop online can create a wish list of products to buy using the software. Its goal is to aid online merchants with big client records by providing at least a simplified self-service option.

The entire purchasing process is automated with a shopping cart system. This statement explains that there is less work for online sellers and a simple transaction for online customers using a shopping cart. Sellers can save time, and money, and keep the customers happy by delegating the task to the shopping cart.

The UML Diagrams of Online Shopping Cart

Here are the UML Diagrams that complete the Online Shopping Cart. Each of the UML Diagrams has a major role in achieving a well-developed and functioning Shopping Cart.

Sequence Diagram

The Sequence Diagram for Online Shopping Cart represents the scenario and the messages that must be passed between objects. This is done for the shopping cart’s functionality to be realized. It’s an interaction diagram that shows how activities are carried out, including when and how messages are sent.

Sequence Diagram for Online Shopping Cart

The online shopping cart sequence diagram has several boxes (objects): the system user, online shopping cart, accounts database, and system interface. Its users could be personnel in an establishment and institutions, and the messages have a flow showing the alternative in every decision.

The explanation for the online shopping cart discusses how the illustration works. It has the figures which will clarify the sequence of activities and their alternatives. The box figures represent the object, the stick man is for the user, and the broken lines are for the lifelines. Vertical arrows then present messages.

Activity Diagram

The UML activity diagram for shopping cart represents the project’s behavior in terms of its activities. It contains the important details on the activities and constraints done in the project. It is one of the methods used for project development. It represents the system’s major activities and constraints that lead to paths that the project includes. They were labeled properly to guide programmers and users.

UML Activity Diagram for Online Shopping System

Online Shopping Cart UML Activity Diagram is one of the methods used for project development. It represents the system’s major activities and constraints that lead to paths that the project includes. They were labeled properly to guide programmers and users about the behavior of the online shopping cart.

Additionally, the activity diagram depicts software operations as a series of actions. These diagrams are used to document and define the system processes and use cases. It can clarify difficult use cases to simplify and improve any process. An activity diagram also models the system’s actions, functions, and processes.

UML Class Diagram

The Class Diagram for Online Shopping Cart is a designed diagram that shows the system’s classes (data) and their relationships. This diagram is similar to a flowchart in which classes are represented by boxes with three rows inside. The top rectangle holds the class’s name; the middle rectangle contains the class’s properties, and the bottom row contains the class’s operation (methods). 

UML Class Diagram for Online Shopping Cart

The illustration of a class diagram informs the project proponents on what are the characteristic (structure) of the software by showing the classes that will be included in the project. It resembles a chart in which classes represent the requirements needed for the online shopping cart to operate correctly.

Use Case Diagram

The UML Use Case Diagram for Online Shopping Cart is a structural illustration of the software’s processes that helps programmers in its development. Use Case Diagram shows the processes included in E-commerce Web or App as well as its users. It serves as the blueprint or core of the said system that will be the basis for building it.

This content discusses and clarifies the Use Case Diagram for Online Shopping Cart with Explanation. It contains the main use cases and users in the system. These use cases are elaborated by either use case connected to them by the broken arrows.

UML Use Case Diagram for Online Shopping Cart

The broken arrows are indications that the following diagrams connected to them are parts of a process. They could either be one of the indications which were the include or extend. The “include” indication means that the following use case should be performed to finish the task and the “extend” indication is otherwise.

The diagram shows the use cases in the online shopping cart. The processes mentioned can be modified and added with other ideas related to the online shopping cart. Your project use cases depend on the processes that your project requires.

Component Diagram

The component diagram for online shopping cart is an illustration of how the system components work together to make the system operate correctly. It shows how the software’s parts are organized and how they depend on each other. This diagram also gives a high-level look at the parts of a system.

This component diagram of online shopping cart is the illustration of the components of every hardware and software node. The component diagram below is a detailed illustration of other diagrams for the shopping cart.

UML Component Diagram for Online Shopping Cart

The Online Shopping Cart UML component diagram explains the sketch of the required software and hardware components and the dependencies between them. These components are labeled to clarify their part in the system’s operation. They were represented by symbols that explain their function and role in the overall processing system operation.

The system’s component diagram has 8 components. Each of these components has its part in the online shopping cart. The system’s components were the sellers and/or admin’s device, shopper’s device, user login interface, product database, carts database, sales database, orders database, and transaction database.

Deployment Diagram

The UML deployment diagram for online shopping cart is used to describe the system’s operations, showing the hardware and software components that run in each node, and explaining the connections between them.

The online shopping cart 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.

UML Deployment Diagram for Online Shopping Cart

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 users’ device, the system front-end interface, the system hosting (online server), and the system back-end.
