A metamodel-based system for automatically generating reports is provided. Much of the work involved in creating report designs and reports is automated, allowing developers to produce a broad variety of report designs and reports in a fraction of the time required with standard report development, according to one illustrative embodiment. Metamodels for data and style templates may be created, that allow for the automated design and manipulation of report models. The report models may be used to generate reports that include the indicated data, arranged according to indicated data field properties, settings, and style templates. Changes made in the metamodels can automatically be reflected in reports designed according to those metamodels.
