This question already has an answer here:
Regard this review. I used normalization instead of normalisation.
Google says "Normalisation is the process of taking data from a problem and reducing it to a set of relations while ensuring data integrity and eliminating data redundancy. Data integrity - all of the data in the database are consistent, and satisfy all integrity constraints."
And "Database normalization, or simply normalization, is the process of organizing the columns (attributes) and tables (relations) of a relational database to minimize data redundancy."
Can you explain it in formal way, please?
