erwin Data Modeler (erwin) is a software tool for data modeling (data requirements analysis, database design, etc.) of custom developed information systems, including databases of transactional systems and data marts. erwin's data modeling engine is based upon the IDEF1X method, although it now supports diagrams displayed with information engineering notation as well. Logic Works stylised "erwin" from an abbreviation of "Entity Relationships" and Microsoft's "Windows".
erwin is the market leading solution with over 30% market share per an October, 2015 analyst report.[1]
History
erwin (formerly, ERwin) was created by Logic Works. It was acquired in 1998 by Platinum Technology, which was later acquired in May 1999 by Computer Associates, who added it to their AllFusion suite under the name AllFusion ERwin Data Modeler. The tool was later renamed to CA ERwin Data Modeler.
In 2014 Embarcadero Technologies sought to acquire the product from CA, Inc..[2] This acquisition was blocked by the Department of Justice over anti-competitive concerns.[3]
As of April 5, 2016, Private equity firm Parallax Capital Partners completed the acquisition of data modeling software erwin from CA Technologies. It now operates as erwin, Inc., and is led by IT industry veteran Adam Famularo, who is now CEO of erwin, Inc.[4]
