<quote> Why is Kdb so fast? The main reason is that Kdb tables are "inverted", i.e. the data in each column is stored together, instead of in the row orientation used by most RDBMS's. The column data is also organized for optimal processing speed. </quote> ./Jason -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
