For many developers, entity-relationship (ER) modeling and relational database design go hand in hand. But a growing number of designers have found database design nirvana using another methodology known as Object Role Modeling (ORM). ORM uses English sentences to express how objects relate to one another, and what constraints and business rules apply to these relationships. While based on techniques dating back to the early 1970s, ORM gained popularity with the February 1994 release of InfoModeler, by Asymetrix Corp. (Bellevue, Wash.).
