</a> My hopes are that Drupal will run out of the box, without any setup whatsoever. LOCKs are on their way out, killes is nurturing the no lock patch I abandoned. And even if they do not die, they are there only to avoid some races which simply do not happen on the small sites that are targets for SQLite (ie. quite small sites).

<br><br>Back on topic, referential integrity is the way forward. Not only does it make us friends with the PostgreSQL folk, but it is good practice in general to have it, regardless of the underlying database engine.<br><br>
The debate about RI is a non-debate. It is a historical issue. There was a database used by hosting companies called mSQL (mini SQL) and it was not free, MySQL stepped in to fill the gap with a free database (as in cost-free initially), with the same syntax, ...etc.. MySQL's popularity skyrocketed, then it became free (as in liberty). They argued that RI is not necessary since web apps are mostly read intensive, and they shined in the read intensive arena.
<br><br>Now, true databases all have RI. MySQL themselves had InnoDB, and most hosting companies for the last 2 years or so support InnoDB. If only Oracle would not have nabbed that, it would have been the way forward. Now they are developing Falcon and solidDB, ...etc.
<br><br>Regardless, RI is needed. <br><br>+1.<br></div>
