Database Normalization

Database normalization is a process used to organize data in a database efficiently. It involves structuring the data in a way that reduces redundancy (duplicate data) and improves data integrity (accuracy). By dividing large tables into smaller, related ones and defining relationships between them, normalization helps ensure that each piece of information is stored only once, making it easier to manage and update. Think of it like organizing a filing cabinet: instead of having multiple copies of the same document, you create categories and link related files, improving clarity and reducing confusion.
