"logical variaibility"

Dawn,

No matter how you toss or turn it, if you design/define a database you *WILL HAVE TO* answer the "range" question for each and every individual attribute in your database. Is 50 ft a possible length for a human person to have ? Is 800 pounds a possible weight for a person ? Is a first name consisting of 1234 tokens a possible first name for a person ? Is a 26-character string a possible zip code in a foreign address ?

At the logical level, which you claim your question is about, string lengths are just a specific appearance of the more general "What's the domain of valid values" question. Received on Mon May 29 2006 - 13:06:22 CEST
