A model is a representation of the business data of an organization or business segment. You can use a model as the basis for your story. Use the Modeler to create, maintain, and load data into models.

Models complement datasets. Datasets are more suitable for ad-hoc analysis, while models are more suitable for governed-data use cases.

If you're not sure whether to use a dataset or a model for your story, this might help you decide: Models vs. Datasets.

If you're more interested in datasets, not models, see Datasets.
