Re: [lookup] speed sales pitch
This WebDNA talk-list message is from 2003
It keeps the original formatting.
numero = 53531
interpreted = N
texte = >2. WebCat databases work well, even when they get big, but can get >bogged down with doing date searches, and number searches to a >lesser extent, since the data must be interpreted then compared. This is why I have always been a proponent of storing dates as "days since 0000" because then you can do a simple text search on a date field and it doesn't bog down. This works great for dates that create a "days since 0000" value of 6 digits, which includes dates in anyone's current lifetime. But if you are using a date range that does not create a 6-digit string - such as dates far in the past or a long time in the future - then you would need to do a mathematical comparison of the "days since 0000" value, which is still less overhead than interpreting date stored as formatted MM/DD/YYYY values. -- Sincerely, Kenneth Grome ------------------------------------------------------------- Outsource your WebDNA programming for $18 an hour or less! ------------------------------------------------------------- ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
