If you have done any data modeling for any major organization, chances are that you have used ERWin Data Modeler at some point in time.
However, ERWin is a very expensive tool for independent consultants or small businesses, therefore, many companies look for cheaper alternatives such as Microsoft Visio.
Well, there is good news for those companies with relatively small databases!
Computer Associates now is offering a free version of ERWin called CA ERWin Data Modeler Community Edition! http://erwin.com/products/data-modeler/community-edition
This version has a limit of 25 objects as well as requiring to re-download the software every 6 months or so to renew the license, but for being able to leverage the full power and functionality that accompanies CA ERWin Data Modeler is well worth it!
