Normal forms are structured representations of data that aim to reduce redundancy and dependency in relational databases, ensuring data integrity and efficiency. They are achieved through a series of increasingly strict rules or 'normalizations', each building on the last, to organize data into relational tables that minimize duplication and potential anomalies.

Reducing Dependency

Relational databases are structured systems that store data in tables with rows and columns, using a schema to define relationships between different data entities. They enable efficient data retrieval and manipulation through SQL queries, ensuring data integrity and consistency using ACID properties.

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle, ensuring that it remains unaltered and trustworthy for decision-making and analysis. It is crucial for maintaining the credibility of databases and information systems, and involves various practices and technologies to prevent unauthorized access or corruption.
