What process is used to link two tables in a database?

The process used to link two tables in a database is accurately described as a join. A join operation allows for the combination of rows from two or more tables based on a related column between them. This is fundamental in relational database management systems as it enables the retrieval of data that is distributed across multiple tables, providing a way to consolidate and analyze related data seamlessly.

For example, in a scenario where you have one table containing customer information and another table with order details, a join operation can be utilized to link these tables by the customer ID. This allows you to create a comprehensive view that includes both customer details and their respective orders.

The terminology surrounding linking tables can vary; however, "merge," "link," and "connect" do not specifically describe the operation of combining rows based on matching columns. These terms may be used informally in other contexts but do not reflect the standardized terminology used in database management systems. Consequently, "join" is the most precise and widely used term for this process.
