ER Diagram for Student Enrollment System

The student enrollment system’s ER diagram shows the relationships of the student enrollment entities in its database design. This describes the logical structure of the system’s database or data storage. It is done by figuring out the entities in the student enrollment process, their properties, and how they work together.

The database design is sketched out using student enrollment system ER diagrams. This database sketch becomes the actual basis of the system’s data storage that will serve as both a data destination and a source.

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 the ER diagram.

The student enrollment system’s ER diagram aims to answer the student enrollment database design. The system’s function is to encode customer information and transactions.

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. The use of the ER Diagram for the Student Enrollment System is needed.

Importance of ER Diagram

The importance of the ER diagram for the 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 the 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.

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.

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 it gathers important information about the enrollees. This data was used to keep track of their transactions and other important system details.
  • Manage Courses and Subjects: The information about courses and subjects is critical in this system.The subjects were assigned to every course that is offered in a school. Assigning the subjects could be made easier and faster with this system.
  • Manage Instructors: This system should be dependable when it comes to assigning instructors in a specific subject. And the assignment of instructors must be included in making the ER Diagram for the 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 timetable.

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 requirements of the system and provide much more specific details of each entity within the system.

The tables given will be the basis for developers on how they will create the student enrollment system database design. It has the complete description of the database.

They will put this into the program or data storage the same as the names given to each of the tables. They will create a database with the attributes given as well as the value of each attribute.

Steps in building the ER Diagram for Student Enrollment System with Cardinality Ratio

  • Step 1: Become acquainted with the ER Diagram (Entity Relationship Diagram).Symbols and Cardinality

    The 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 familiar 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 quality. 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 
    – A foreign key is produced when data attributes have one too many relationships with other entities.

  • Step 2: Complete the entities that will be included.

    Start designing your ER Diagram by finalizing the entities that must be included in your bank’s 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.

  • Step 3: Add each entity’s attributes.

    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. All of these are examples of attributes. Multivalued attributes can be assigned to several values.

  • 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 on the evaluated information to have the exact entity relationship diagram.


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 the 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.
