Database normalization is a process used to organize a database into tables and columns to reduce data redundancy and improve data integrity. It involves dividing large tables into smaller, related tables and defining relationships between them to ensure data dependencies make sense and are logical.

Data redundancy occurs when the same piece of data is stored in multiple places within a database or data storage system, which can lead to inconsistencies and increased storage costs. While sometimes intentional for backup and performance reasons, excessive redundancy can complicate data management and compromise data integrity.

defining relationships

Data dependencies refer to the relationships between different data elements where the output or state of one element is influenced by the input or state of another. Understanding these dependencies is crucial for optimizing data processing, ensuring data integrity, and designing efficient algorithms and systems.

Logical relationships are the connections between ideas or propositions that determine the validity of arguments and the coherence of thoughts. Understanding these relationships involves recognizing patterns such as causation, correlation, and contradiction to effectively analyze and construct logical arguments.
