ER Diagram for the University Management System

In DBMS, ER diagram for a university management system shows how the databases are connected to each other. It also shows how all the databases are logically related to each other. We can also create an ER diagram by drawing the figure of a different part of the university management system and their properties and how they perform their task.

We can draw an ER diagram of the university management system by drawing the design of the database. The sketch of the database became the storage of the database where the data comes and goes.

Details University Management System ER Diagram

Now we describe the overall function of the University Management System in the below table. It is a complete overview of the information about the university management project.

Name: ER Diagram of the University Management System.
Abstract: The ER Diagram of the University management system shows the relationship between various entities. We can also call it the blueprint of the University management system.
Diagram: We can also call the ER diagram an Entity Relationship diagram.
Tool used: The ER diagram provides some symbol that is known as the diagramming tool.
Users: The users of the ER diagram are university admin , applications, software, and websites.

What is University Management System?

A University management system is a web-based solution that covers all the functions of a university and college. It is developed for analyzing, conducting, and monitoring the complex activity of the university and affiliated colleges like admission, examination, and many more.

Importance of University Management System

When we compare the manual process with the university management system, the university management system makes easier the overall process of the university management system. The university management system creates a platform that collaborates with all students, administrators, faculty, and stakeholders. Some key benefits of the university management system are as follows.

  1. It is very easy for the student to access information and educational service.
  2. It provides transparency in all the processes.
  3. It provides better communication between all the stakeholders of the university.
  4. All the tasks are executed in a very simplifying matter.
  5. The pre and post-examination works have the management of the time-critical activity.

What is an ER Diagram?

We can also call ER diagram the database design for the university management system project. The ER diagram is like a picture that contains how all the entities are related to each other. The most important part of the ER diagram is Relationships, Attributes, and Entities.

Importance of ER Diagram

The ER diagram for the project is the foundation for the building of the database of the project. The properties, datatypes, and attributes are defined by the ER diagram.

ER Diagram for University Management System

The ER diagram for the university management system, the system data, and their attributes. The data and the attributes are represented by the table, and the table shows how they are related to each other.

Database Design for the University Management System

ER Diagram for the University Management System

The above diagram shows the database design for the university management system. This database design shows all the system data, and the output for the user is stored in the database. In DBMS, a good ER diagram is needed for the creation of a university management system.

University Management System ER Diagram Tables

The below table shows all about the field name of the table, description, datatype, and character length. Each table of the ER diagram defines and explains the data storage.

The field column lists all the attributes of the database that describes each column. The types table of the database shows what kind of data each attribute is, and the length shows how many characters it has.

Table Name: Student

Field Description Type Length
stud_ID (PK) Student ID Int 11
Stu_name Student Name Varchar 255
Stu_mob Student Mobile Number Int 11
stu_add Contact Address Int 11
stu_email Student Email Varchar 255
stu_pass Student Password Varchar 255

Table Name: Course

Field Description Type Length
crs_ID (PK) Course ID Int 11
crs_name Course Name Varchar 30
crs_desc Course Description Varchar 30
Crs_type Course type varchar 30
Crs_std_ID Student ID int 11

Table name: college:-

Field Description Type Length
Col_ID College ID int 11
Col_desc College description varchar 255
Col_type Type of the college varchar 30

Table name: registration:-

Field Description Type Length
Reg_stu_ID Student registration ID int 11
Reg_ID Registration ID int 11
Reg_desc Description about registration varchar 255
Reg_type Type of registration varchar 30
Reg_date Date of registration varchar 30

Table name: permission

Field Description Type Length
Per_id Permission id varchar 255
Per_role_id Permission role id varchar 255
Per_module Permission module Varchar 255
Per_name Permission name Varchar 255

Table name: Roles

Field Description Type Length
Role-id Role id varchar 255
Role_name Role name varchar 255
Role_desc Role decription varchar 255

Table name: Log-In

Field Description Type Length
Login-ID Login ID Varchar 255
Login-role-ID Login-role ID Varchar 255
Login_username User name Varchar 255
Login_password Password Varchar 255

Table name: users

Field Description Type Length
User_id User id Varchar 255
User_name Name of the user varchar 255
User_mobile Mobile number int 18
User_email Email id varchar 255
User_address address varchar 255

With the help of the above tables, we can set up the database for the university management system. It provides the full description of the database with its table names. They will enter all the values and attributes for the database in the table.

How to create ER Diagram

We can create the ER diagram for the table just in 5 minutes. There are some steps, and with the help of these steps, we can build the ER diagram for the university management system project. The steps are as below.

Step 1: We must familiarize ourselves with the entity relationship diagram cardinality and symbols. Then we have to show the data structure for the project in the entity relationship diagram. The symbol of the entity relationship diagram shows how they fit together. Before making the ER diagram, we should properly know the meaning of all the symbols and how to use all of them symbols.

Symbol of entity relationship diagram:-

  1. Fields: This entity shows how the different types of data are used together for a project. The symbol is used to show how the part of the project is working.
  2. Key: It is a type of technique that is used to categorize the quality of the data. There are two types of keys available for the database. These are as follows.
    • Primary key: It is a set of unique properties that are used for finding the specific entity.
    • A foreign key: It is a type of key made up of a piece of data with too many links to other things.

Step 2: Finalize the entities included

Start making your ER Diagram by deciding on all the parts your university management system must have. You'll need to leave the area in your design for these rectangles to be included later.

Step 3: Add the attributes of each entity

After you've decided on the entities, think about the traits you'll need for each one. In a conceptual ER diagram, the details of the different entities are given as attributes. Attributes are things like a thing's traits, a many-to-many relationship, or a one-to-one relationship. Attributes with multiple values can be given more than one value.

Step 4: Describe the relationships (cardinality) between entities and attributes

You will need the entities, their attributes, and the relationships between them to plot the relationships between the ERD. To get the right entity relationship diagram, you will use the information you gathered to build the data structure.


You need to know how the University Management System was designed and built using diagrams. With the help of an ER diagram will help you make a system that works well. Making it will help you understand how the software works behind the scenes. This is where all the data that goes in and out of the system will be stored.
