The DEFAULT command is used to define a default value for a column in a table. This value will be used when no other value is provided for the column during insertion. The other options (CHECK, UNIQUE, NOT NULL) are used for different purposes such as enforcing constraints or setting limitations on the values that can be inserted into a column.
