texte = 534Hi Brian! I take back your example about the date in a database: =leMODDATEdata=3D12/31/2015You explain that someone who would write "yesterday" would jeopardize =the database integrity. We are in the case where a date can be freely =written. So, imagine we get a date in European format, 31/12/2015, which =is also the format adopted by 90% of the countries in the world (the =format MDY is only US-based), or number written alternatively as =9,210.00 (US) o 9.210,00 (European). Let=E2=80=99s talk about zip code, =US based is a number with a "-" that would prevent this field to be =treated as a number, english one could be C178AN, or the phone numbers =with international +39 or +1, or inventories with text and numbers?Also, what about the "grouping fields", if you mix numbers with text? I =also saw programs using dates in the format 12/31/16 (1916 or 2016?).We would have to think a way to specify each format in the database =header, which would further restrict the use of the database by implying =a *lot* of specific cases, while a simple test in the code could easily =make all data searchable and make usable an heterogeneous database, a =privilege that no other database system offers.I think it is little effort to add DeadlineType=3Ddate and that =introducing restrictions in database format would just be introducing =limits to creativity and flexibility.- chris> That being said, I completely disagree when it comes to storing and =retrieving information in a data structure. If i have a field in a data =structure (read: SQL data table or WebDNA database) that is for storing =dates, then allowing someone to store "yesterday" is nonsensical and =causes problems when I try to retrieve dates based on a calculation. =(i.e. leMODDATEdata=3D12/31/2015) Of course I should write code that =stops this data from being stored in the first place, but as a last =resort the database program itself should defend the database to protect =the integrity of the data stored in it. The side effect, which almost =outweighs the protection factor to be candid, is that when retrieving =info, if each field has a predefined data type, the database already =knows how to deal with searches so the programmer doesn't have to =reiterate for each search that this field is a date, or a number, or =whatever.=20---------------------------------------------------------This message is sent to you because you are subscribed tothe mailing list
