What are the differences between gta online and the gta v single player story?

The only evidence supplied is an excerpt from the Wikipedia article on the development of Grand Theft Auto V. That passage covers the team size, release dates, and the studios involved, but it does not discuss gameplay modes, narrative structure, or any distinctions between the online multiplayer component and the single‑player campaign. Because no verifiable details about the differences are present, it is not possible to answer the question based solely on the provided evidence.
