UML Diagram for Online Bike Service Booking System

UML diagrams for the Online Bike Service Booking Project. Below are the Components, Activity, Use Case, and Sequence UML diagrams of the online Bike Service system project.

The Online Bike Service  Booking Management application will help to manage the shop. It allows the shop owner to manage the day-to-day process of a Bike Service Booking conveniently.

UML Diagram for Online Bike Service Booking System

We’ve compiled structural UML diagrams i.e. component diagrams, and three types of behavioural UML diagrams i.e. Activity, Sequence, and Use Case diagrams for the Online Bike Service Booking Project. We have also explained the data flow diagram (DFD) for this project.

Here, we have two users, who will be interacting with the system. With the help of these diagrams, one can get a better understanding of the project. This web application is developed to provide users with an online medium where they can shop for different types of Bike service parts. Admin is who will manage the overall application; whereas the user or customers can buy Bike Service products.

Component diagram for Online Bike Service Booking Project

The component diagram below shows the structural relations between components in an Online Bike Service Booking System. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely product, order, customer, and account.

It shows how the user component connects to the other components while using the system.

Once the customer logs in to the system, the customer can select the desired product and place an order request following the payment process. While placing the order, the customer’s account details get accessed and the order is confirmed after completing the payment. Users can download invoices and bills for purchases made.

Activity diagram for Online Bike Service Booking Project

Activity diagrams in UML display the functionalities of various activities and flow in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.

Admin can view the list of bookings. Admin can manage the category of products and can update all product detail. Admin can view booking history and detail. Admin can manage payment and invoices.

Online customers can browse or search items, view specific items, book them, view, add to cart, and checkout. Users can view booking history at any time. Users can make payments for the booking and view the payment history.

Sequence diagram for Online Bike Service Booking 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 a selected product, add the product to the cart, and make payments for the booking. After completion of payment, the user can view and download invoices.

Use Case Diagram for Online Bike Service Booking 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.

It can be seen from the below diagram, 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 parts, view stocks, and different products and categories of products into the system. Whereas, users can access the system for booking services. Users can access the ‘share feedback’ use case.

DFD Diagram for Online Bike Service Booking 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 a system’s users and process flow work.

After logging in, both Admin and Customer will land on the home page where they can manage their profiles. Admin can add, view products, manage prices of products, view bookings, check the availability of the product, etc.

Customers, on the other hand, can book services online. Customers can search for particular products, and also view their bookings and payment confirmation on the system.
