This question seems so basic that I can't believe I'm asking it. But, here's the deal- another developer and I both installed the latest SQL Developer Data Modeler. I created a Relational Model of our database. It's pretty, beautiful, likely to get me awards in the modeling community. (Ok, it isn't.)
But now I need to email it to my coworker. I went to the location where File --> Save goes and the file is there (Whatever.dmd). The file is only about 1kb and is a simple XML file:
<?xml version = '1.0' encoding = 'UTF-8'?>
<OSDM_Design class="oracle.dbtools.crest.model.design.Design" name="Whatever" id="8BBCF442-1A47-2660-D210-5A3C6C178DDF" version="3.5">
<createdBy>myinitials</createdBy>
<createdTime>2016-07-08 17:00:44 UTC</createdTime>
<ownerDesignName>Whatever</ownerDesignName>
<capitalNames>false</capitalNames>
<designId>8BBCF442-1A47-2660-D210-5A3C6C178DDF</designId>
</OSDM_Design>
When she opens it, there's nothing there (nothign under "Relational Models". I've also tried going to File --> Export --> To Data Modeler Design, but the same 1kb file is generated.
So... what am I doing wrong? (And please assume that email is the only solution for transferring these design files- no matter how terrible that is.)
