Normalized Schema
A normalized schema is a database design approach that organizes data into multiple related tables to minimize redundancy and ensure data integrity. It involves structuring data according to normalization rules (typically up to the third normal form or higher) to eliminate duplicate information and dependency issues. This concept is fundamental in relational database management systems (RDBMS) for efficient and reliable data storage.
Developers should learn and use normalized schemas when designing relational databases for applications that require data consistency, such as financial systems, e-commerce platforms, or enterprise software, to prevent anomalies during data operations like insertion, update, or deletion. It is particularly important in scenarios with complex data relationships and high transaction volumes, as it reduces storage costs and improves query performance by avoiding data duplication.
