UML diagrams for the Restaurant Management System.

UML diagrams for the Restaurant Management System. Following are the different UML diagrams like Components, Activity, Use Case, and Sequence diagrams of the Restaurant Management System.

The Restaurant Management application will help to manage the shop. It allows the shop owner to manage the day-to-day process of Restaurant management and bookings conveniently.

UML Diagram for Restaurant Management 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 Restaurant Management System. 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 Restaurants can be managed properly. Admin is who will manage the overall application; whereas the staff can add tables for customers.

Component diagram for Restaurant Management System

The diagram below shows the structural relations between components in a Restaurant Management System. The connected components by lines represent relationships within the systems. In the diagram, it can be seen that there are components namely  Restaurant, booking, customer, and account.

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

Admin can ADD/VIEW/DELETE/UPDATE Categories Information. Admin can ADD/VIEW/DELETE/UPDATE Product Information. Admin can ADD/VIEW/DELETE/UPDATE Company Information. Admin can ADD/VIEW/DELETE/UPDATE User Information i.e. Staff. Admin can VIEW/UPDATE its own Information. Admin can VIEW Total products, total Users, and total Stores. Admin can add/delete/update tables and stores from the system.

Activity diagram for Restaurant Management System

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 users. Admin can manage the category of food and can update all  Restaurant detail. Admin can view booking history and detail. Admin can manage payment and transactions.

Staff can view booking history at any time. Staff can add orders for customers and generate invoices for customers.

Sequence diagram for Restaurant Management System

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.

Admin can manage the category of food and can update all  Restaurant detail. Admin can view booking history and detail. Admin can manage payment and transactions. Admin can ADD/VIEW/DELETE/UPDATE Product Information, Tables, and Stores.

Use Case Diagram for Restaurant Management System

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 within the entire process (and where they’re excluded).

For example, Admin will be able to add different products(food items) and view a list of products in the system. Admin will have the responsibility to add tables, staff, etc. Whereas, Staff can access the system for Restaurant system to take orders, view available tables, view order bookings, payments, etc.

DFD Diagram for Restaurant Management System

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.

After logging in, Admin and Staff will land on the home page where they can manage their profiles. Admin can add, view restaurants, manage prices, view bookings, check the availability of the tables, add tables, food, users, etc.

Staff, on the other hand, can take the orders of customers in the restaurant online. Staff can also view products, tables, orders, and payment confirmations on the system.
