I have table with column "ACTIVE" where my application stores the values
of checkbox: 'Y' or 'N' (checked/unchecked). Although my application
cannot store any other value than 'Y' or 'N', question is; is it good
practice to have the additional check constraint checking if the value
of "ACTIVE" column is in domain ('Y','N') or this is just waste of
maintenance time and database performance because every time before
inserting or updating database has to check if the new data for "ACTIVE"
column is in ('Y','N') domain?
