UML Diagram for Online Books Shop System

Components, activities, Use Cases, and Sequence(UML) diagrams for Online Book Shop Management System.

The Online Books Shop Management application will help to manage the shop, users, books, and bookings. The whole idea behind the application is to manage the orders and transaction details related to the bookstore. let’s understand the flow and user role and create different types of UML diagrams.

UML Diagram for Online Books Shop 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 Books Shop Project.

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 books. There are multiple roles in this application. One is the Admin, who will manage the overall application, and another is the user or customers who can buy Books.

Component diagram for Online Books Shop Project

The component diagram below shows the structural relations between components in an online Books shop system. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely product, book, customer, and account.

It shows how the user component connects to the other components while using the system. Everything from the account details to product booking to payment flow can be seen in the component diagram.

Users can view all the books, search books by name, filter books by categories, and buy or download books after login into the application.

Activity diagram for Online Books Shop Project

Activity diagrams in UML are a leading subset of behavioral diagrams. They display the functionalities of various activities and flows in management processes and software systems. The flow in the activity diagram can be sequential, branched, or concurrent.

Admin can view the list of Users. Admin can manage the category of Books and can update all product detail. Admin can view booking detail. Admin can manage payment and transactions.

Online Users can browse or search items, view specific items, book them, view and checkout. Users can view booking history at any time. Users can make payments for the booking and view the payment history. Users can also download free book PDFs.

Sequence diagram for Online Books Shop Project

Sequence diagrams in UML are used to get a better idea of how tasks within a project will function, overlap, and move between objects or components. Sequence diagrams display step-by-step interactions between objects and the order in which those interactions occur.

Online users can search for products, view the price of a selected product, add the product to the shopping cart, and make payments for the booking. Users will also get an option for downloading free books PDFs.

Use Case Diagram for Online Books Shop 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.

From the below diagram, we can see that Admin can access Add Book and Book List use case. Whereas users can access book lists, buy books, and download books use cases. Login, Logout, and My Profile use cases are common for both users.

DFD Diagram for Online Books Shop Project

A DFD maps out the flow of information for any process or system. It gives a basic overview of the whole system or process being analyzed. It shows the system with its relationship to external entities.

In the diagram, we can see that Admin and User must be logged in to the system. Both Admin and User will land on the home page after logging in where they can manage their profiles, viewbooks, check prices of books, view cart, etc. Admin manages the selling history, which is the bookings made by the users. Users can also view their bookings and payment confirmation on the system.
