Hi Don, Have a look at EOEntity and friends: EOAttribute, EORelationship.
You can build them out and setup the “external” name for the column, etc. I did it once as an exercise many moons ago. The only practical use I got out of it was sometimes sanity checking keyPaths to see if they hit things “in memory” or if they were completely traversable through EOEntity relationships. Something that trips an in-memory method call is not something you can use to build a complex SQL query. Like other people have said, the “reverse engineering” of the original WO tools is more likely what you want to use instead. You point Entity Modeler at a database and it can make a surprisingly good model file from it. Depending on how big the database is… it might be worth your trouble of firing up MacOS Tiger and installing the NeXTStep GUI tools to do the reverse engineering. I don’t think that the Eclipse java based EntityModeler can reverse engineer. I don’t know if Cayenne can reverse engineer.
