In SQL relational databases, the VARCHAR data type is used to store variable-length strings. It can hold a sequence of characters with a specified maximum length, allowing for efficient storage by only using as much space as needed for the actual string length. The maximum length can typically be defined when creating the column, for example, VARCHAR(255) allows for strings up to 255 characters long. This flexibility makes VARCHAR a popular choice for storing textual data.
