title: visibility of variables in SQLiteOpenHelper android
body: <p>why on all demos and tutorials in SQLiteOpenHelper class variables are always: <strong>public static final</strong></p>
  
  <p>Have a look:</p>
  
  <pre><code>    public static final String ORDER_ID = "order_id";
      public static final String ORDER_LOGIN_NAME = "login_name";
      public static final String ORDER_RESTO_U_NAME = "resto_uniqe_name";
  </code></pre>
  
  <p>My question is: I am making an application and its database is too big. So, I will have to make atleast 60-70 variables of these kind. Won't it affect application performance? As these are static variables.</p>
  
  <p>Any help will be highly appreciated....</p>
