Laravel 5 CRUD Error

I`m new to the laravel.so i implement CRUD function.but it gives me 2 errors.one is this.

ErrorException in UrlGenerator.php line 304: Route [Item.store] not defined. (View: C:\xampp\htdocs\demo\resources\views\Item\create.blade.php)

Here is my index function.

  public function index()
{
    $items = Item::all();
    // return $items;
    return view('Item.index', compact('items'));  
}

Here is my Store Function.

  public function store(Request $request)
    {
       item::create($request -> all());
        $item = new item;
        $item ->service = $request ->service; 
        $item ->unit = $request ->unit;
        $item ->boq_no = $request ->boq_no;
        $item ->boq_qty = $request ->boq_qty;
        $item ->save();

             Item::create($request->all());
                return redirect()->route('item')
                        ->with('success','Item created successfully');
    }
