Relational Database Models

A relational database model organizes data into tables, which are composed of rows and columns. Each table represents a specific entity, like customers or orders, and the columns hold attributes of that entity, such as names or dates. Relationships between tables are established through unique identifiers called keys, allowing for efficient data retrieval and management. This model offers flexibility, ensures data integrity, and supports complex queries, making it a popular choice for structured data storage in applications ranging from websites to enterprise systems.
