Final answer:

Database normalization involves organizing data to reduce redundancy and redundant connection, progressing through various normal forms.


Explanation:

Database Normalization:

  1. First Normal Form (1NF): Segments data to avoid repetition, eliminating repeating groups and attributes by placing them into separate tables connected via primary keys and foreign keys.

  2. Second Normal Form (2NF):

    Eliminates redundant data through specification and ensures connections between tables facilitated by foreign keys.
  3. Third Normal Form (3NF): Requires all fields in a table to directly relate to the key or the concept of that table, preventing redundant data.
