The Practical Database Design: Building a Blog Schema with RDBMS Fundamentals course provides a complete, practical introduction to designing efficient and scalable relational databases. Using a hands-on, project-based approach, you’ll learn how to translate real-world requirements into a well-structured database model — one that can power a modern web application like a blog.

The course begins with a deep dive into the core principles of database design, introducing essential terminology such as databases, RDBMS, entities, attributes, and the data lifecycle. You’ll explore why database design is crucial for data integrity, performance, and application scalability. Each concept is explained in simple terms, building a strong foundation before you move into the project phase.

Next, you’ll apply these principles to a real-world project: designing a blog database schema. You’ll start by identifying key entities such as users, posts, comments, and ratings, and then associate attributes and relationships to create a meaningful structure. Using tools like Lucidchart, you’ll design an Entity Relationship Diagram (ERD) that visually represents how your database tables interact.

As you progress, you’ll learn about normalization and field structuring, moving through First, Second, and Third Normal Forms (1NF, 2NF, and 3NF) to eliminate redundancy and ensure data consistency. You’ll gain hands-on experience resolving multivalued and composite fields, defining primary and candidate keys, and establishing dependencies that enhance database performance.

The course also focuses on table relationships, guiding you through one-to-one, one-to-many, and many-to-many associations. Through a series of guided projects, you’ll learn how to build logical connections between tables to support efficient data retrieval and reporting.

Finally, you’ll move into advanced implementation topics, including user interactions, flagging systems for objectionable content, comment management, and rating functionality. By the end of the course, you’ll have built a fully functional and normalized blog database — ready to integrate into any application.

This course not only teaches the theory behind database design but also helps you think like a real-world database architect. You’ll understand how to design systems that are flexible, maintainable, and optimised for performance across all major RDBMS platforms.
