I suspect they're misapplying the lesson Google taught everyone. Namely that domain-specific solutions can provide much better performance than general-purpose software. Google might not use an RDBMS to store their search index (which doesn't need any of the ACID guarantees and needs all kinds of parallelism and lossy alorithms which SQL and RDBMSes in general don't excel at), but on the other hand I would be quite surprised if they stored their Adsense or other more normal use data structures in anything but a bog-standard SQL database. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org/
