What Are Candidate Keys In Database Normalization? Are you interested in understanding how databases organize and identify data efficiently? In this video, we’ll explain the concept of candidate keys in database normalization. We’ll start by defining what candidate keys are and why they are essential for creating reliable and consistent databases. You’ll learn how candidate keys help uniquely identify each record in a table, acting like a fingerprint for data. We’ll also cover the criteria that make a set of columns qualify as a candidate key, including the importance of minimality and uniqueness. Additionally, we’ll discuss how candidate keys are used in the normalization process to eliminate duplicate data and prevent errors, ensuring your database structure is clear and effective. You’ll see how candidate keys influence the selection of primary keys and how they support the relationships between tables through foreign keys. Understanding candidate keys is fundamental for designing well-structured databases that perform efficiently and maintain data integrity. Whether you're a beginner or an experienced developer, grasping this concept will help you build better database systems and improve data management practices.
