An example of an AI chatbot conversation about database normalization techniques and examples.
What are some examples of database normalization?
Database normalization is a process to organize data in a database. Examples include 1NF, 2NF, and 3NF.
Can you explain what 1NF is?
1NF, or First Normal Form, requires that all columns contain atomic values and each entry in a column must be of the same type.
What about 2NF?
2NF, or Second Normal Form, builds on 1NF by ensuring that all non-key attributes are fully functional dependent on the primary key.
Can you give me a practical example of 3NF?
Sure! In 3NF, a table is in 2NF and has no transitive dependencies. For instance, if you have a table with student IDs, names, and their advisor's name, you should separate the advisor into a different table.
