ER Diagraming Software (Are there any good ones?)

Path: emory!swrinde!cs.utexas.edu!usc!elroy.jpl.nasa.gov!ames!agate!boulder!reetz From: reetz@news.colorado.edu (Mike Reetz) Newsgroups: comp.databases.informix Summary: Need a good ER Diagram Tool/Schema Design Tool Keywords: ER Schema Design Diagram Message-ID: <1992Mar4.163325.3909@colorado.edu> Date: 4 Mar 92 16:33:25 GMT Sender: reetz@morse.colorado.edu Organization: University of Colorado, Boulder Nntp-Posting-Host: morse.colorado.edu I'm looking for an ER (Entity Relationship) Diagramming Tool. I have looked at a few (ERwin for one) and was not too impressed. What I'd like to see is a program that uses the database itself as its description and from the database schema (and some DB designer input...like relationships between entities, primary keys, foreign keys...) be able to produce ER diagrams. Other niceties would be the ability to change the diagram and have the database schema changed also, or change the schema in some other way (via SQL for example) and have these changes reflected in the ER Tool's "database". Has anyone had experience with such a tool??
