      From: nospam@nospam.org              Personally, I am in favour of putting database handling in its own       classes or even a separate layer. It helps you switch databases if you       ever want to, and I usually do want to in my unit tests.       No method is "absolutely correct". You can represent the whole database       structure in an object layer, but in some cases that could be too much       work with no gain.       If you find yourself typing (or pasting) duplicate code, like database       handling code, you can refactor that code into its own class and refer       to an instance of that class.       In general, you can always refactor a working design into a better       designed situation, so don't fix yourself on starting perfectly.              Lots of databases have optimizations, but they can be different. Know       your database. I know MS-Access and SQL server can handle repetative       simple commands well (but in different ways). Especially if you are       writing for different database types, you'd best stick to simple       commands or abstract database commands to specific objects for the       database types.              Best regards              Jack wrote:       > Hello,       > VB6.
