What is the recommended format for birth year in Oracle?

The recommended data type for storing birth year in Oracle is the NUMBER data type. This allows for the year to be stored as a numerical value and allows for mathematical operations to be performed on it if needed. Additionally, you can set a constraint to ensure that the birth year falls within a certain range, such as between 1900 and the current year.
