SQL Developer

Friends,

I'm trying to understand the differences between Oracle SQL Developer Data Modeler and the ability to use the Data Modeler in SQL Developer.

I've looked at both products home pages on OTN, http://www.oracle.com/technology/products/database/datamodeler/index.html & http://www.oracle.com/technology/products/database/sql_developer/index.html and would appreciate your comments on my findings so far

1) The Oracle SQL Developer Data Modeler is a stand-a-lone chargeable product whereas the use of the Data Modeler functionality of SQL Developer is free

2) The Data Modeler functionality within SQL Developer is basically a "viewer" I can create ERD's of my existing tables by dragging them into the modeler from the object navigator but that's about it. I can't save the diagram for later use or use it to change the structure of the table(s)

3) If I need to have "Oracle Designer" like ERD capabilities then I need to use Oracle SQL Developer Data Modeler (after purchase!)

4) Are there any other differences I have missed?


Thanks in advance
