What is 1NF?
An example of an AI chatbot conversation about the First Normal Form in database design.
Can you explain what 1NF is in database design?
Sure! 1NF, or First Normal Form, is a property of a relation in a relational database. It requires that all attributes in a table contain only atomic, indivisible values.
What does it mean for values to be atomic?
Atomic values are those that cannot be divided further. For example, a column for 'Full Name' should be split into 'First Name' and 'Last Name' to meet 1NF.
Why is 1NF important?
1NF is important because it helps eliminate redundancy and ensures that the data is structured in a way that makes it easier to query and maintain.
Can you give me an example of a table that is not in 1NF?
Certainly! A table that has a column for 'Hobbies' with multiple values like 'Reading, Swimming' in a single cell is not in 1NF. Each hobby should be in a separate row.
