In SQL, what does the term "Normalization" refer to?*Creating indexes on tables for faster retrievalOrganizing data in a database to reduce redundancyRemoving duplicate rows from a tableOptimizing database performance
Solution
Normalization in SQL refers to the process of organizing data in a database to reduce redundancy and improve data integrity. This is achieved by dividing larger tables into smaller tables and defining relationships between them. The main goal of normalization is to eliminate redundant data, which can save storage space and ensure consistency within the database. It's important to note that normalization is not about removing duplicate rows from a table or creating indexes for faster retrieval, although these can be part of broader database optimization strategies.
