Which term describes data that come from many different sources in various structures?

Disparate data accurately describes information that originates from a variety of sources and may be presented in different formats or structures. This term highlights the challenges that organizations face when trying to integrate and analyze data that does not come from a singular or uniform system. The diversity in the sources, formats, and structures can complicate data management and make it difficult to derive meaningful insights effectively.

While unstructured and semistructured data refer to the organization of the data itself, disparate data focuses on the variety of sources and their inherent differences. Source data simply refers to the original data acquired for processing, which may not emphasize the complexity of coming from various origins. Therefore, the term 'disparate data' is most appropriate in this context for describing the scenario outlined in the question.
