Relational Database Schema
A relational database schema is a blueprint that defines the structure, organization, and constraints of a relational database. It specifies tables, columns, data types, primary keys, foreign keys, and relationships between tables, ensuring data integrity and consistency. This schema acts as a logical framework that guides how data is stored, accessed, and manipulated in systems like MySQL, PostgreSQL, or Oracle.
Developers should learn relational database schema design when building applications that require structured data storage, such as e-commerce platforms, content management systems, or financial software, to ensure efficient queries and data accuracy. It is essential for implementing ACID properties, optimizing performance through normalization, and facilitating scalable database management in enterprise environments.
