Question

Im new using Sql Developer data Modeler, I made a Model using this tool but I dont Know how to re-open cause SqlDeveloer has created XML files, The app has created a folder that contains two folders: map and rel, map contains two files:

Answer 1

Solution,

I was created New relational model Design,

Looked up for main project File, I copied the main file from the damaged project and change next lines:

   <relationalModel class="oracle.dbtools.crest.model.design.relational.RelationalDesign"    name="PreciosModel" id="CF6F32EB-1ADF-A4D4-42E5-1871F2A3D75A" mainViewID="1A7856BA-66B4-D0E8-BF00-0204C3F41BBB">

  </relationalModel>
