FitTrack: Fitness Database Design and Implementation


Welcome to our blog post! Today, we are thrilled to delve into another exciting project requirement titled "FitTrack: Fitness Database Design and Implementation." In this post, we will thoroughly explore the intricacies of this project requirement, outlining its scope and detailing our approach to tackle it effectively. Join us as we embark on this journey to revolutionize fitness management through database excellence.

Project Requirement : 


You will design and create a database for "FitTrack". You will begin by creating dependency diagrams to identify the relationships between different data elements and to ensure that the database is properly normalized. From there, you will use the diagrams to create an entity-relationship diagram (ERD) that accurately represents the structure of the database. The ERD should include no fewer than 12 entities, such as users, workouts, exercises, goals, achievements, and social connections. Once the ERD is complete, you will use it to create the physical database schema and implement the necessary SQL statements to create the tables, relationships, and constraints in the database.

You will need to come up with your own business rules to create entities and relationships. Here are some example business rules that you can use:

  • Each user can have multiple workout plans, and each workout plan can contain multiple exercises.

  • Each exercise can be associated with one or more muscle groups, and each muscle group can be associated with multiple exercises.

  • Each workout can be assigned a difficulty level, which can range from beginner to advanced.

  • Each user can set and track multiple fitness goals, such as weight loss, muscle gain, or endurance improvement.

  • Each goal can be associated with one or more metrics, such as weight, body fat percentage, or distance.

  • A workout can include multiple exercises and use specific equipment.

When converting your ERD entities to tables, insert no fewer than 5 rows of data in each table. 

Once you have completed the creation of your fitness tracker database, you should also create at least five views that display key information from the database. Views are useful because they allow users to see information from multiple tables in a single place and can help simplify complex data relationships.

One view idea could be a "Top Exercises" view that displays the most popular exercises performed by users across the platform. This view could show the top 10 exercises ranked by the total number of sets or reps completed across all users in the database. Other potential view ideas could include a leaderboard of top performers in a given fitness challenge or a breakdown of workout data by muscle group.

Constraints & Clarifications


  • All entities must be in 3NF.

  • Entities and attributes should be named using the same naming scheme we have been using in class (all uppercase and snake case).

  • ERDS should show weak/strong relationships, PKs and FKs, optionality, named relationships, and be well formatted (your ERD should not look like I dropped spaghetti on the floor). No M:N relationships can exist.

  • No multi-valued attributes can exist.

  • Ensure foreign keys are established in your database.

Solution Approach 

In this section, we will delve into the solution approach adopted to complete the project tasks outlined above. We will discuss the methods, techniques, and strategies employed to design and implement the FitTrack: Fitness Database Design and Implementation.

  • Dependency Diagrams:

  • Create dependency diagrams to visualize data relationships.

  • Ensure proper normalization and identify dependencies.

  • Entity-Relationship Diagram (ERD) Design:

  • Translate dependency diagrams into an ERD.

  • Include entities like users, workouts, exercises, goals, achievements, etc.

  • Define strong and weak relationships, PKs, FKs, and optionality.

  • Ensure ERD is well-formatted and comprehensible.

  • Physical Database Schema Implementation:

  • Convert the ERD into a physical database schema.

  • Write SQL statements to create tables, relationships, and constraints.

  • Implement business rules and constraints.

  • Ensure all entities are in 3NF and follow naming conventions.

  • Data Insertion:

  • Populate the database with sample data.

  • Insert at least 5 rows of data in each table.

  • Verify data integrity and consistency.

  • View Creation:

  • Design at least five views to display key information.

  • Views should simplify complex data relationships and provide useful insights.

  • Implement views such as "Top Exercises" or fitness challenge leaderboards.

  • Testing and Validation:

  • Test database functionality and views thoroughly.

  • Validate data consistency and accuracy.

  • Ensure views provide the expected information.

Output :

In this section, we will showcase some output screenshots obtained after completing the aforementioned project tasks. These screenshots will demonstrate the successful execution and outcomes of the FitTrack: Fitness Database Design and Implementation.
