Database Design and Data Management Foundations

Data is the backbone of modern software, but poorly structured data leads to slow performance and maintenance headaches. This text-only course guides you through the fundamental principles of database design, helping you transition from chaotic spreadsheets to clean, efficient, and normalized relational databases. You will learn to: 1. Understand core database concepts, including tables, keys, and data integrity. 2. Design entity-relationship diagrams to map out real-world data requirements. 3. Apply normalization techniques to eliminate data redundancy. 4. Write foundational SQL queries to create tables and manage data. 5. Compare relational databases with modern NoSQL alternatives. 6. Learn best practices for basic indexing and schema migrations. We start with essential database terminology and theory before moving into structural modeling and schema design. This course is designed for absolute beginners, aspiring data professionals, and software developers with no prior database experience. Start building a solid foundation in data management today.
