'''erwin Data Modeler''' (stylized as '''erwin''' but formerly as '''ERwin''') is
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.

ERwin was created by [[Logic Works]], which was based in [[Princeton, New Jersey]].<ref name=":0">{{Cite news|url=http://www.pcworld.com/article/2108620/embarcadero-moves-into-data-modeling-with-ca-erwin-buy.html|title=Embarcadero moves into data modeling with CA ERwin buy|last=Jackson|first=Joab|date=2014-03-14|work=PCWorld|access-date=2017-10-02|language=en}}</ref> In May 1993, Logic Works released ERwin/ERX, a version of the tool designed to work in conjunction with [[PowerBuilder]].

Beginning in 1992, the [[United Nations Development Programme]] (UNDP) was one of the larger organizations to utilize ERwin to integrate its many independent databases located at its 120 field offices. UNDP used ERwin to develop a “corporate data model”, with the goal of “reducing redundant data entry” and create a single database framework based on which “all future systems can be designed”. ERwin was used to both reverse-engineer existing data at field offices and also move data from Computer Associates’ [[IDMS]] to [[Sybase]]’s UnixRDBMS.<ref>{{Cite news|url=https://books.google.com/books?id=81WcX8nG1uUC|title=U.N. group globalizes data modeling|last=Hoffman|first=Thomas|date=1993-08-09|work=Computerworld|access-date=2017-09-02|pages=69, 74}}</ref>
As of 2001, the insurance company [[Aetna]] used Erwin Data Modeler to automate maintenance of its [[Table (database)|database table]] definitions. Aetna’s database consisted of 15,000 table definitions which became difficult to maintain manually.<ref>{{Cite news|url=http://www.computerworld.com/article/2592300/financial-it/managing-tons-of-data.html|title=Managing Tons Of Data|last=Nance|first=Barry|date=2001-04-23|work=Computerworld|access-date=2017-10-02|language=en}}</ref>
