Great Minds Think Alike.  :)

Yes, this sounds right; or even, table-centric vs. record-centric.

Yes, that sounds exactly right.

Here's another example (hopefully more clear) as to how  
Solar_Sql_Model works:

     // get an instance of a Model
     $model = Solar::factory('Solar_Model_Nodes_Wikis');

     // work with one Record from the Model
     $record = $model->fetch(1);
     foreach ($record->revisions as $revision) {
         $revision->dump();
     }
     $record->subj = 'Something';
     $record->save();

     // work with a RecordSet from the model
     $recordset = $model->fetchAll(array(
         'where' => array('area_id = ?' => 1),
     ));
     foreach ($recordset as $record) {
         echo $record->subj;
     }

     // work with the Model as a whole
     $data = array('status' => 'public');
     $where = array('area_id = ?' => 1);
     $model->update($data, $where);

That last one, "work with the Model as a whole", is a key feature; in  
Solar, you should be able to access the Model (i.e., the table and  
its relationships) directly if needed.
