| Resumen≠ | Database normalization is a systematic process for organizing relational database schemas to eliminate redundancy and enforce data integrity. Introduced by Edgar Codd in 1970-1971 as part of the relational database model, it defines a series of normal forms (1NF through BCNF) that progressively eliminate different types of data anomalies. | Entity-Relationship (ER) modeling is a conceptual approach to database design that represents real-world entities, their attributes, and the relationships between them. Introduced by Peter P.-S. Chen in 1976, ER modeling provides a high-level graphical notation (ER diagrams) that bridges the gap between informal requirements and formal database schemas. |
