Relational Database Design and Student Enrollment Systems

Designing efficient, reliable databases is an essential skill for software development, data administration, and backend engineering. This text-based course guides you step-by-step through relational database principles using a practical student enrollment system as your core case study. You will begin with essential terminology, entity-relationship concepts, and table design before learning how to structure complex relationships between students, courses, instructors, and enrollments. What you'll learn: - Understand core database terminology, table structures, and data types - Model one-to-one, one-to-many, and many-to-many relationships accurately - Apply normalization principles to eliminate redundancy and maintain data integrity - Write foundational SQL queries to insert, update, retrieve, and filter enrollment data - Define primary and foreign keys to enforce relational constraints - Practice indexing and basic query structuring for optimal performance The course moves logically from conceptual database modeling to practical SQL implementation through clear written explanations and structured schema examples. Designed for complete beginners, no prior database experience or programming background is required to get started. Begin reading today to build robust relational databases from the ground up.
