The first step in making the Gym Management System is to make the ER diagram, which will be used as a starting point when making the database itself. We will make the entity relationship diagram for the Gym Management System and explain how it is made.

The ER diagram gym management system project is a set of information systems that run a gym or other place to work out and exercise.

Based on the image above, the Entity-Relationship Diagram for Gym System is the blueprint of the Gym System database, and these are presented in tables. The tables are made to meet the required specification of the system and provide much more specific details of each entity within the system.

The purpose of this ER Diagram is to fully understand the Gym Management System as well as the relationships of tables in the project database design. And if you like to have a reference for your project making, you can have the PDF copy of this Gym Management System ER Diagram.

Gym Management System Database Design

This Gym Management System database design was made based on managing Gym requirements. The system can secure and monitor the activities and advise exercises for the gym clients and their sessions or time schedules. The gym admin can have access to the clients’ status, checking their activities, and secure the clients’ every activity.

The features included in this Gym Management system’s ERD were securing and monitoring the card holders’ transaction records and status. These features were also listed and recorded in reports that served as the history of all the activities done in the system.

Gym Management System ER Diagram Tables

These tables below provide the complete database table details such as Field NameDescriptionsdata types, and character lengths. Each of these tables represents the characteristics and the attributes of data storage.

The field column presents the names of each database’s attributes, the description column gives the complete thought of each attribute, the type column is their data type and the length is for their character lengths.

The tables given will be the basis for developers on how would they do the gym management system database design. It has the complete description of the database and 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.

How to create an Entity-Relationship (ER) Diagram

Time needed: 5 minutes

Here are the steps on how to create Gym Management System ER Diagram

  • 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 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 are 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. 

    A 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.

    Begin designing your ER Diagram by finalizing your railway reservation system’s entities. These are rectangles. You must leave room in future phases so they can be incorporated.

  • Step 3: Add the attributes of each entity

    Upon finalizing the entities, analyze their attributes. As characteristics, ER diagram entities are described. All these are characteristics. Multivalued characteristics have several values.

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

    Entities, characteristics, and relationships are needed to draw ERD relationships. The data structure and entity relationship diagram are based on evaluated information.


ER (entity-relationship) diagram is only one of the diagrams used to design and develop the Gym Management 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.
