I've not been to that place but one colleague (ex-job) describe it this way : The developpers only know the objects, they're not aware of the tables. All the locking and relation between the objects is done at the application server level. The application server generates the sql to read/write the tables. So for them a database or a a file, they do not care.
I have to start reading about objects, j2ee, xml, uml, java, ... and I thought I would have time to go snowboarding during the Christmas time ;-) --- [EMAIL PROTECTED] a �crit : > Just because the development tools are object > orientated does not mean that the > database has to be as well. > > Dick Goulet > > ____________________Reply > Separator____________________ > Subject: RE: Object relational features and > performance > Author: =?iso-8859-1?q?Stephane=20Paquette?= > <[EMAIL PROTECTED]> > Date: 12/20/2002 9:04 AM > > Is this the future ??? > > I know one big bank where the development is object > oriented and the database (DB2 UDB in this case) is > used as a big flat file.
