Various Formats: Unstructured data can be stored in a variety of formats – from a mp4 video to a genomics BAM file to a .log diagnostics file to an X-RAY image that may be stored as a digital PACS format, all of these are types of unstructured data. So, an accurate way to describe unstructured data is that it has a variety of formats and not just one format. This means more applications can generate unstructured data and tailor the format to their use.
