Database Design and Management Fundamentals

Dealing with unstructured or inefficiently stored data can halt development and lead to major performance issues. Effective database design is the foundation of any reliable application or information system. This course teaches you the core principles required to design, implement, and manage relational databases from scratch. You will move past simple data storage and learn how to structure data logically, ensuring integrity, efficiency, and scalability for real-world projects. What you'll learn: * Understand the core concepts of data persistence, relational models, and the role of ACID properties in transaction management. * Master the process of conceptual and logical data modeling using Entity-Relationship (ER) diagrams. * Apply normalization techniques (up to BCNF) to eliminate redundancy and ensure data integrity within your schema. * Practice writing Data Definition Language (DDL) and Data Manipulation Language (DML) for creating tables and managing data records. * Configure basic indexing strategies and understand query optimization fundamentals to improve database performance. We begin by defining database terminology and exploring relational theory. We then walk step-by-step through the design process, from initial requirements gathering and ER modeling to applying normalization rules and translating the design into a functional schema. This course is designed for absolute beginners interested in software development, data analysis, or system administration. No prior experience with SQL or database systems is required.
