title: joomla assets table purpose
body: <p>could you please explain to me what is the purpose of <strong>assets</strong> table in joomla?</p>
  
  <p>I have script for import articles from <code>.csv (from .xls)</code> that just inserts new rows in content table with <code>asset_id</code> column (foreign key) set to <code>0</code>. </p>
  
  <p>I haven't find any problems with articles that have assets id set to 0. Anyway, I'd like to know if this could cause any problems or disable some functionality.</p>
