title: Should I write table and column names ALWAYS lower case?
body: <p>I wonder if it's a problem, if a table or column name contains upper case letters. Something lets me believe databases have less trouble when everything is kept lower case. Is that true? Which databases don't like any upper case symbol in table and column names?</p>
  
  <p>I need to know, because my framework auto-generates the relational model from an ER-model.</p>
  
  <p>(this question is not about whether it's good or bad style, but only about if it's a technical problem for any database)</p>
