erwin Data Modeler (stylized as erwin but formerly as ERwin) is computer software for data modeling. Originally developed by Logic Works, erwin has since been acquired by a series of companies, before being spun-off by the private equity firm Parallax Capital Partners, which acquired and incorporated it as a separate entity, erwin, Inc., managed by CEO Adam Famularo.

The software’s engine is based on the IDEF1X method, although it now also supports diagrams displayed with a variant information technology engineering notation, as well as a dimensional modeling notation.
