使用する際の注意点

• This word is more often used as an uncountable noun with a singular verb than as a plural noun with singular datum. The latter is almost entirely restricted to formal contexts.
• The definition of data in the computing context is from an international standard vocabulary and is meant to distinguish data from information. However, this distinction is largely ignored by the computing profession.[1]
