Normalization in MySQL is the process of organizing data into tables in such a way that the data is stored efficiently and redundancies are minimized. Normalization is an important concept in database design, as it helps to ensure data integrity and reduce data storage requirements.
For example, if a database contains information about customers and orders, the data can be normalized by creating separate tables for customers and orders. Each table would contain the relevant information about customers and orders, and the two tables could be linked together using a foreign key. This would ensure that the data is stored efficiently and redundancies are minimized.
