Joomla 3 component MVC model, adding article directly to the database -

i beginner both when comes using mvc , creating joomla components. need create component reads uploaded csv-file contains article data, , add them directly database.

so far i've created barebone component uses example of adding article directly database found here, , i've tried implement using mvc structure, i'm not sure if i'm doing correctly.

the component based on com_helloworld component tutorial on how create basic component, explain structure, , can tell me whether i'm doing seems reasonable or not.

so when open component adminstrator panel in joomla, goes default view in

com_helloworld/admin/views/helloworld  

view.html.php loads nothing corresponding model, , opens default.php in

com_helloworld/admin/views/helloworld/tmpl 

default.php contains:

<?php?> <a href="index.php?option=com_helloworld&view=jimport">add article</a> 

so clicking link opens view jimport, has following view.html.php:

<?php defined('_jexec') or die('restricted access'); class helloworldviewjimport extends jviewlegacy {         function display($tpl = null)         {                 // status model                 $this->status=$this->get('status');                 parent::display($tpl);         } } 

and following default.php in tmpl folder:

<?php echo($this->status); 

the view jimport calls function getstatus() corresponding model in com_helloworld/admin/models/jimport.php, contains following code:

class helloworldmodeljimport extends jmodellist {      public function getstatus($type = 'jimport', $prefix = 'helloworldtable', $config = array()) {         $table = jtable::getinstance($type, $prefix, $config);         $title='article';         $alias=$title;         $introtext='this article has been added automatically database through component';         $catid=2;         if ($table->addarticle($title, $alias, $introtext, $catid)) {             return "the article has been added.";         } else {             return "there error.";         }     }  } 

in other words, getstatus tries add article database , returns string telling whether succesful or not.

now function gets instance jtable implementation in

com_helloworld/admin/tables 

which contains jimport.php:

class helloworldtablejimport extends jtable {      /**      * constructor      *      * @param   jdatabasedriver  &$db  database connector object      */     function __construct(&$db) {      }      public function addarticle($title, $alias, $introtext, $catid) {         if (version_compare(jversion, '3.0', 'lt')) {             addincludepath(jpath_platform . 'joomla/database/table');         }          $article = $this->createarticle($title, $alias, $introtext, $catid);          // check make sure our data valid, raise notice if it's not.         if (!$article->check()) {             jerror::raisenotice(500, $article->geterror());             return false;         }          // store article, raise notice if doesn't stored.         if (!$article->store(true)) {             jerror::raisenotice(500, $article->geterror());             return false;         }         return true;     }      private function createarticle($title, $alias, $introtext, $catid) {         $article = jtable::getinstance('content');          $article->title = $title;         $article->alias = jfilteroutput::stringurlsafe($alias);         $article->introtext = $introtext;         $article->catid = $catid;         $article->created = jfactory::getdate()->tosql();         ;         $article->created_by_alias = 'super user';         $article->state = 1;         $article->access = 1;         $article->metadata = '{"page_title":"","author":"","robots":""}';         $article->language = '*';          return $article;     }  } 

this article added database, , pretty explains entire component.

i know if seems reasonable way this. i'm not sure if should model, or if article should added through controller.

this basic question, , have been trying figure out on own, haven't found example particular case.
