[PHP-DB] Efficiency of DDD programing

[Fanda]

Hi,
how to solve this problem:

If I write a repository for each entity, article and autor for example, article 
is composed of autor and some other things, then I want to select some articles:

$articles = $articleRepo->findLast(10);
foreach ($articles as $article) {
    // echo article content
    ...
    // echo
    $article->getAutor(); // next query into database, in each cycle
}

Is some elegant way, how to do this (optimise)?

Thank you.
F.
