That database is part of the internal coding of MySQL.

INFORMATION_SCHEMA provides access to database metadata.

Metadata is data about the data, such as the name of a database or table, the data type of a column, or access privileges. Other terms that sometimes are used for this information are data dictionary and system catalog.

INFORMATION_SCHEMA is the information database, the place that stores information about all the other databases that the MySQL server maintains. Inside INFORMATION_SCHEMA there are several read-only tables. They are actually views, not base tables, so there are no files associated with them.

In effect, we have a database named INFORMATION_SCHEMA, although the server does not create a database directory with that name. It is possible to select INFORMATION_SCHEMA as the default database with a USE statement, but it is possible only to read the contents of tables. You cannot insert into them, update them, or delete from them.

That database is part of MySQL and can be ignored. It shouldn't be deleted though, but it doesn't count towards disk space usage, nor does it count towards your database usage.
