Opakovane nacitani dat z DB

Zdravim mam problem s tim, ze mam tridu Team, kde si zjistuji informace o tymu, mimo jine podle uzivatele zjistuji i team_id z DB. A tuto metodu pak volam z ruznych casti aplikace. Problem je ale v tom, ze pri kazdem zadani se mi vzdy data tahaji z DB. Da se to nak vyresit aby se to nacetlo jednou a pak uz se to tahalo jen z pameti?

team

class TeamModel extends Object {

    /** @var \Nette\Database\Connection */
    private $database;

    /** @var Nette\Security\User */
    private $user;

    /**
     * @param Nette\Database\Connection $database
     * @param Nette\Security\User $langModel $user
     */
    public function __construct(\Nette\Database\Connection $database, \Nette\Security\User $user) {
        $this->database = $database;
        $this->user = $user;
    }


    /**
     * Podle uzivatele vrati id tymu
     * @return int $tym_id
     */
    public function getTym_id() {
        return $this->database->table('tym')->where('uzivatel_id', $this->user->id)->fetch()->id;
    }

volani:

class Foo extends Object {

    /** @var \Nette\Database\Connection */
    private $database;

    /** @var Nette\Security\User */
    private $team;

    /**
     * @param Nette\Database\Connection $database
     * @param Nette\Security\User $langModel $user
     */
    public function __construct(\Nette\Database\Connection $database, \TeamModel $team) {
        $this->database = $database;
        $this->team = $team;
    }

    public function neco() {
	$data = $this->team->tym_id;
    }
