What is a Student Enrollment System?
An online student enrollment system can centralize all of the data in one place, making it simple to access and amend. Registration information is immediately uploaded to the database, so there is no need to type it in by hand.
The Student Enrolment System is a cloud-based system that is meant to manage all of the actions involved in the student enrollment process. The main goal of the enrollment system is to help staff members sign up students and keep track of their information.
What is an ER Diagram?
The ER Diagram is referred to as the student enrollment system database design. This ER diagram is the graphical depiction of relationships between all the entities involved in the system. Its major components are Entities, Attributes, and Relationships.
In DBMS, the student enrollment system ER Diagram is used to build and troubleshoot relational databases. It works best with DFD (Data Flow Diagram), which is responsible for data movement. Designing the student enrollment system database would be much easier with the help of ER diagram.
The student enrollment system ER diagram aims to answer the student enrollment database design. The system’s function is to encode customer information and transaction. Also, the student enrollment admin must have access to the enrollee’s information for reports and monitoring purposes. The data used in these transactions must be managed and secured well and the use of ER Diagram for Student Enrollment System is needed.
Importance of ER Diagram
The importance of ER diagram for student enrollment system is to help in modeling its data storage or database. It is the basis of the project’s database foundation for construction. This entity-relationship diagram (ERD) also aids in defining the data types to be stored such as their attributes and characteristics.
In addition to that, the ER Diagram also describes how an entity interacts with other entities. 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 student enrollment system is used in conjunction with its data flow diagram. They are very important in building a relational database because they let us visualize how data is connected generically.
Entity-relationship diagrams are utilized in software engineering during the planning phase of software development. It aids in the identification of various system constituents and their interrelationships. Student Enrollment System ER Diagram is also used as the foundation of its DFD (Dataflow Diagram)
The database design for student enrollment system is the same as its ER diagram. They were used to emphasize the student enrollment system database or data storage to determine the data to be stored and their attributes. This is to inform developers about the system’s structure in terms of data storing.
Student Enrollment System Database Design
This student enrollment system database was made based on student enrolling requirements. The system can encode enrollees’ information. The registrar admin can have access to the enrollees’ status and information for the important transactions. They can handle the data needed in managing enrollment and enrollees’ information as well as the transactions made.
The features included in the system ER diagram were the security and monitoring of the enrollee’s transactions and enrollment status. These features were also listed and recorded in reports that served as the history of transactions done in the system.
Student Enrollment System Features:
- Enrollment Management – The process of enrollment includes some considerations such as choosing courses, crediting subjects, and assigning instructors that correspond to the enrollees’ year level.
- Enrollee’s Management – This feature plays a big role in the system because this gathers important information about the enrollees. This information was used to track their transactions and other important matters regarding the system.
- Manage Courses and Subjects – The courses and subjects information are important to handle in this system. The subjects were assigned in every course that is offered in a school. Assigning of the subjects could be made easier and faster with this system.
- Manage Instructors – This system should be reliable with the assigning of the instructors in a specific subject. And the Assigning of instructors must be included in making the ER Diagram for Enrollment System.
- Transaction and Reports Management – This feature will store the transactions made by the customers including their information and the reports of every transaction and timetables.
Entity Relationship Diagram for Enrollment System
ER Diagram of Enrollment System shows the system entity relationships in each entity and their supposed functions in each relationship.
Based on the image above, the ER diagram for this System is the entity of the Enrollment system database, which is presented by tables; students, courses, enrollment, school year, subjects, and instructors.
The tables are made to meet the required specification of the system and provide much more specific details of each entity within the system.

Steps in building the ER Diagram for Student Enrollment 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:
• Fields: Fields 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 bank 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 reservation 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 bank reservation system er diagram. These attributes can be a primary key or a foreign key in the database design of the project. Your 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.
You need to know the diagrams used to design and develop the Student Enrollment System. That is to help you create a fully-functional system with the use of ER Diagram. Creating it will help you perceive the back end of the software. This will hold all the data that’ll enter and exit the system.
