Some words are used as same in plural form.
ex: information, data etc.
like this, the word "software" can be used ? (what is the plural form of software )
Only if you want to be pedantic and show off. Its Latin origins notwithstanding, the word data has evolved in the English language.* It's uncountable and takes a singular verb.As far as I know, "data" is the plural of "datum"
*similarly to the word media, although media can be used as singular or plural
