Normal forms

Normal forms are guidelines in designing databases to organize data efficiently and reduce errors. They ensure data is stored logically, minimizing duplication and making updates easier. Think of them as steps to tidy up a filing system: each step builds on the previous one to improve clarity and consistency. By following these forms, a database avoids redundant information, keeps related data connected properly, and maintains integrity—meaning the data remains accurate and reliable over time. Overall, normal forms help create a well-structured, reliable database that supports effective data management.
