A relational database is a type of database that organizes data into tables consisting of rows and columns. It is based on the relational model of data management, which was first proposed by Edgar F. Codd in the 1970s. The relational model establishes relationships between tables using keys, enabling efficient and structured storage and retrieval of data. In a relational database, each table represents an entity or a concept, and the columns in the table represent attributes or properties of that entity. Each row in the table represents a specific instance or record of that entity. For example, in a database for a company, you might have a "Customers" table with columns like "Customer ID," "Name," "Address," and "Email." The relationships between tables are established through keys. A primary key is a unique identifier for each record in a table, while a foreign key is a reference to a primary key in another table. These keys create links between related tables, allowing data to be retrieved and combined from multiple tables using queries. Relational databases offer several advantages.
