Data normalization

Data normalization is a process used to organize data in a database to reduce redundancy and improve data integrity. It involves structuring the data in a way that ensures each piece of information is stored only once, which helps eliminate inconsistencies and makes retrieval more efficient. By grouping related data into tables and defining relationships between them, normalization makes it easier to update, manage, and analyze data while ensuring accuracy. Think of it as tidying up a messy room: everything has its place, making it simpler to find what you need when you need it.
