The Relational Database Model is a way to organize data into tables, which consist of rows and columns. Each table represents a different entity, such as customers or orders, and the relationships between these entities are established through shared data, known as keys. This structure allows for easy data retrieval and manipulation using a language called SQL (Structured Query Language). In a relational database, data integrity and consistency are maintained through rules and constraints. For example, a primary key uniquely identifies each record in a table, while a foreign key links records across different tables. This model is widely used in various applications, from business systems to web applications, due to its flexibility and efficiency.
