Creative writing is considered to be any writing, fiction, poetry, or non-fiction, that goes outside the bounds of normal professional, journalistic, academic, and technical forms of literature. Works which fall into this category include novels, epics, short stories, and poems. wikipedia.org

A short story is a work of fiction that is usually written in prose, often in narrative format. This format tends to be more pointed than longer works of fiction, such as novellas (in the 20th and 21st century sense) and novels.

Fiction writing is the composition of not factual texts. Fictional writing often is produced as a story meant to entertain or convey an author's point of view.

An article is a written work published in a print or electronic medium. It may be for the purpose of propagating the news, research results, academic analysis or debate. wikipedia.org
