Railway Reservation System ER Diagram
The railway reservation system ER diagram shows the relationships of the system’s entities that build its database design. This describes the logical structure of the system’s database or data storage. It is done by identifying the railway reservation process entities, their properties, and the interactions between them.
The railway reservation system database design is sketched out using ER (entity-relationship) diagram. This sketch becomes the actual basis of the system’s data storage that will serve as data destination and source.

What is Railway Reservation System?
The railway reservation system enables passengers to inquire about available tickets according to their location and destination, avail of ticket bookings and cancel tickets when needed, and see the status of their booked tickets, and other transactions.
The scope of railway reservation system is to allow passengers to make reservations from any railway station, and they will be updated automatically at all stations. As a result, the reservation crews or admin of the establishments will have no trouble creating the reservation. Maintaining a global database makes this possible.
Railway Reservation System Features
- Railway Reservation Management – Railway Reservation Management is the main feature of this system wherein ER diagram contains the basic details of the system. Its information was composed of the transactions done by the customers, and the accommodation available for reservation.
- Customer Management – This feature plays a big role in the system because this gathers important information about the customers. This information was used to track their transactions and other important matters regarding with the system.
- Manage Railway Information – The railway information management was important for the system because it serves as the basis of the customers as they avail of the reservation offered by the railway. This information was monitored to keep the customers updated.
- Transaction and Reservation Management – Its feature will store the reservation made by the customers as well as the date of the transaction. This will also save and update the accommodate based on the date requested by the customers.
What is an ER Diagram?
In DBMS, the ER Diagram of railway reservation system is also known as the system’s database design. It is the graphical depiction of relationships between all the entities involved in the system. Its major components are Entities, Attributes, and Relationships.
To build and troubleshoot relational databases, the railway reservation system ER Diagram is used. It works best with DFD (Data Flow Diagram), which is responsible for data movement. Developing the database design for railway reservation system would be much easier with the help of ER diagram.
Importance of ER Diagram
The importance of ER diagram for railway reservation system is to help in modeling its data storage or database. It is the basis of the project’s database foundation for construction. The railway reservation system entity-relationship diagram (ERD) also aids in defining the data types to be stored such as their attributes and characteristics.
All other real-world projects are presented with ER Diagrams (database designs). To display the details and attributes of a data store, the er diagram for railway reservation system is used in conjunction with its data flow diagram. It visualizes how data is connected generically.
ERD (Entity-relationship diagram) is utilized in software engineering during the planning phase of software development. It aids in the identification of various system constituents and their interrelationships. Railway Reservation System ERD is also used as the foundation of the railway reservation DFD (Dataflow Diagram).
ER Diagram of Railway Reservation System
The ER Diagram of Railway Reservation System shows the system entity relationships in each entity and their supposed functions in each relationship.
Based on the image above, the entity-relationship diagram for Railway Reservation system database tables was composed of the customer, admin, reservation, train ticket, transaction, transaction type, and reports.
The tables are made to meet the required specification of the system and provide much more specific details of each entity within the system.
Railway Reservation System Database Design
This Railway Reservation system database design was made based on managing reservation requirements. The system can encode customers’ requests regarding railway reservations. Its admin can access the customers’ status and information. It can also handle and update data in reservations and customer transactions.
The features included in the system’s ER diagram were the security and monitoring of the reservations and customers’ records, transactions, and status. These features were also listed and recorded in reports that served as the history of transactions done in the system.

How to create an Entity-Relationship (ER) Diagram
Time needed: 5 minutes.
Steps in building the ER Diagram for Railway Reservation System with Cardinality Ratio.
- Step 1: Familiarize the ER Diagram (Entity Relationship Diagram) Symbols and Cardinality
Entity Relationship Diagram – shows the structure of data types in a project. It uses symbols to clarify its parts and relationships. Their symbols and applications must be familiarized before you build the ER Diagram.
ER Diagram Symbols:
• Field – are the parts of a table that define the entity’s characteristics. In the database that the ERD models, attributes are commonly thought of as rows.
• Keys – is a technique to categorize data qualities. It is used to organize ER diagrams and assist users in modeling their databases to ensure that they are efficient. This is also used to connect different tables in a database.
– Primary Key: identifies a single entity instance which means a unique attribute or set of attributes.
– Foreign Key: is produced when data attributes have one too many relationships with other entities.
ER Diagram Cardinalities:
The styling of a line and its termination demonstrates cardinality and ordinality.
The greatest number of times an instance of one thing can be related to instances of another entity is referred to as cardinality.
While Ordinality refers to the fewest number of times a single entity instance can be linked to another.
- Step 2: Finalize the entities included
Start designing your ER Diagram by finalizing the entities that must be included in your railway reservation system. This entity is represented by a rectangle, and you’ll want to leave plenty of room for them in future phases so you may add them to your design.
An entity set is a group of similar entities with shared properties. A table or a table’s attribute is an entity in a database management system. As a result, by depicting relationships between tables and their characteristics, an ER diagram displays the whole logical structure of a database.
- Step 3: Add the attributes of each entity
After finalizing the entities, think about the qualities you’ll need to characterize each entity. The details of the various entities outlined in a conceptual ER diagram are supplied as attributes. Characteristics of an entity, a many-to-many relationship, or a one-to-one relationship are all examples of attributes. Multivalued attributes can be assigned to several values.
The entity’s attributes were represented by ovals and can be seen in the tables of the railway reservation system er diagram. These attributes can be a primary key or a foreign key in the database design of the project. Yoy ER diagram design could also be converted to the database of the system by declaring your right entities and their attributes.
- Step 4: Describe the relationships (cardinality) between entities and attributes
To plot relationships between the ERD you will need the entities, their attributes, and relationships. You will base the data structure from the evaluated information to have the exact Entity Relationship Diagram.
A relationship is an association that describes how two entities interact. At the connector’s endpoints, the cardinality is indicated by a crow’s foot. One-to-one, one-to-many, and many-to-many are the three most common cardinal relationships. It’s the maximum number of times an instance of one entity can be linked to instances of another entity.
ER (entity-relationship) diagram is only one of the diagrams used to design and develop the Railway Reservation System. Each of the diagrams you design and create will help you in presenting your ideas and impart your abilities.
Creating the ER diagram will help you perceive the back end of the software which will hold all the data that’ll enter and exit the system. To learn more about the ER Diagrams and more, check out the related and recommended articles below.
