Hi,

I’m trying to use UML to model a database and I’m using class diagrams to do so. My attributes keep changing on me when I either add a new attribute or do just about anything besides sit there. Help?

Oh, and I’m using 4.0 GA on 3.1.0 on Linux.

Brian,
Could you give us some more information? Are you saying that when you add an attribute to a class the other attributes change to the default name & type (newAttr:int) ?
Thanks,
Kapil

As I add new attributes, previous ones change. It seems to happen randomly, so I can never expect when it will occur.

To rule out a repaint issue, could you check the properties view if it displays the class info correctly?

It doesn’t appear to me that the MyEclipse UML plugin supports modeling databases very well. It assumes that the user is modeling a Java application. Is it possible that since I’m entering attributes like “ANSWER : CLOB” or “QUESTION : VARCHAR2(4000)” that the tool is performing a validation of some sort and that’s why it’s messing up? I would really like to use this as my DB modeling tool, but I may have to consider using a stand-alone UML tool.

Yes , unfortunately MyUML currently doesnt support your requirement. I’ve filed this as a user feature request internally.
We apologize for the inconvenience.

FYI: We are beefing up our ER Designer which will most likely cover your requirement. That should be out with 4.1.

Hi,

I just checked the most recent feature list for 4.1 and don’t see anything about ER Designer. Is there support in the latest 4.1 release for what I need to do?

[Kapil Kapre]

I will check with the feature team and reply back.

[Kapil Kapre]

Brian,
Looks like the 4.1 release will not have this support as well. Will post more information if we re-prioritize.
Sorry for the inconvenience,
Kapil
