Having designed a profile, at any stage, with a minimum of definitions and customizations, you can quickly and easily generate the schema or sub-model. Depending on the technology chosen and the profile type (schema or transform), the formats presented to you will vary. Note multiple formats can often be generated at once. And, of course, you can repeat the process easily, as the composition evolves or after design changes to the model.

The Schema Composer is supported in the Corporate, Systems Engineering, Business and Software Engineering and Ultimate editions of Enterprise Architect
