UML Diagram for E-commerce shop Project

UML diagrams for the E-commerce (Online Garment Shop) project. There are different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the E-commerce (Online Garment Shop) explained in this article.

UML Diagram for E-commerce System Project

In this article, we have put together the structural UML diagrams i.e. component diagrams, and three types of behavioral UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the E-commerce (Online Garment Shop) Project. We have also covered the data flow diagram (DFD) for this project.

E-commerce (Online Garment Shop) is an e-commerce-based project. This web application is developed to provide users with an online medium where they can shop for different types of Garment items. Admin is who will manage the overall application; whereas the user or customers can buy clothing items.

Component diagram for E-commerce Project

Component diagrams are essentially class diagrams that focus on a system’s components that are often used to model the static implementation view of a system. The components are connected by lines representing relationships within the systems. In the diagram, it can be seen that there are components namely product, order, customer, and account.

As the customer logs in to the system, the customer can select the desired garment product and place an order following the payment process. While placing the order, the customer’s account details get accessed and the order is confirmed after completing the payment.

Activity diagram for E-commerce Project

Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems.

Admin or shop owners can manage the activity of the Online Garment Shop. Admin can manage the category of garment and can update all garment detail. Admin can view booking history and detail.

E-commerce (Online Garment Shop) provides the to view the product according to the categories. Customers can add products to cart options so the user can add the product to the wish list or cart, which means it becomes easy to manage the product while going to pay for it.

Sequence diagram for E-commerce Project

Sequence diagrams in UML are used to illustrate the sequence of messages between objects in an interaction. A sequence diagram consists of a group of objects that are represented by lifelines and the messages that they exchange overtime during the interaction.

Online customers can search for products, view the price of selected clothing items, add the product to the shopping cart, and make payments for the booking.

Use Case Diagram for E-commerce Project

A UML use case diagram can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.

As you can see from the examples below, use cases are represented by oval shapes, and the lines then show at which point an actor/user participates and interacts with their corresponding use case. You can see where each actor is involved in the entire process.

For example, Admin will be able to add managers and different products and categories of garments into the system. Whereas, users can access the system for shopping purposes.

Admin can add the user and can manage the shop, manager, and users. Admin can manage the product record as well.

DFD Diagram for E-commerce (Online Garment Shop) Project

A data flow diagram represents the flow of information for any process or system. It shows the system with its relationship to external entities. Here, we can see how the users and the process flow work in a system.

Admin will manage the overall application. The important objective is to have an application where the garment shop owner can add products, and view total sales. This project has all the necessary functionality from adding and deleting garments from the system.

Managers are one of the users that can access the system.  Managers can add products and view categories of products.

Customers can select any garment product. Customers can search for particular clothing items, and also view their bookings and payment confirmation on the system.
