# Storages

The database related rules are stored under this sub-category of a sink. There is a separate directory for each vendor such as MySQL, MongoDB, etc. At the lowest level, rules are stored as per the programming languages. There will be a file for every language. The rules which are applicable to all the programming languages are stored in the default.rule file.

Directory `rules/sinks/storages`:
