what is a relational database

A relational database is a type of database that stores data in a tabular format consisting of rows and columns, where each row represents a record and each column represents a field or attribute of that record.

In a relational database, data is organized into one or more tables, each with a unique name and a set of columns that define the data that can be stored in that table. Relationships between the tables are established through the use of foreign keys, which allow data to be linked and retrieved from multiple tables.

Relational databases are widely used in various applications, including accounting, customer relationship management, inventory management, and many others. They offer several advantages over other types of databases, such as scalability, flexibility, and ease of data retrieval and manipulation.
