Visio 2002 and Chen ER Database Diagrams

According to TechNet ... the Chen ERD shapes have been "subsumed" into the Database Model Diagram:

"Visio 2002 Professional does provide you with features that let you generate ER diagrams, but, instead of Visio 2000 Professional's six, or Visio 2000 EE's seven, you only get three choices: Database Model Diagram, Express-G, and ORM Diagram (see Figure 6). Basically, the Bachman, Chen, and Martin ER diagrams have been subsumed into the Database Model Diagram, but Visio 2002 Professional does provide all of the shapes you need to create logical models using today's popular ER and IDEF1X notations. (IDEF1X is a method for designing relational databases with a syntax designed to support the semantic constructs necessary in developing a conceptual schema. For more about IDEF1X, see www.idef.com/idef1x.html or buy Thomas Bruce's 1992 classic Designing Quality Databases With IDEF1X Information Models [ISBN 0932633188].)"
