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.

How to create an Entity-Relationship (ER) Diagram

Time needed: 5 minutes.

Steps in building the ER Diagram for Gym Management 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 gym management 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 gym management 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.

Conclusion:

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.
