# Faceted classification

> Unlike classification by a single system, such as file-manager folders or biological taxonomy, faceted classification uses several independent classification systems at the same time. It is mainly used to classify digital information.

Unlike classification by a single system, such as file-manager folders or biological taxonomy, faceted classification uses several independent classification systems at the same time. It is mainly used to classify digital information.

For example, when booking a film, classification by cinema location (e.g. Seoul/Yongsan/IMAX), by film (e.g. drama/Small Things Like These), by screening time (e.g. Monday/2 p.m.), and by country of production (e.g. foreign production/Ireland) can be applied independently of one another.

It offers greater flexibility and scalability, but makes information management more complicated.
