- I wouldn't expect Oracle to hype DAL over one of its own products, would you?!? The
- downside of using SQL*Net is that all your front-end applications are hardwired into
- Oracle, which is of course exactly what Oracle wants. Having used DAL extensively on
- several projects, I would be the first to say that it isn't a dream. However you
- are almost wholly independent of the back-end, be it Oracle, Sybase, Ingres, etc.
-
- If you go into building your front-end applications with something like DAL, you gain
- the ability to scale these applications well: start them off with a server on an A/UX
- box, move it to a VAX, and on and on.
-
- On the other hand, if you are an Oracle shop and have support contracts, etc, and are
- not planning a migration or diversification soon, probably SQL*Net is the way to go
- simply from the point of simplicity of support.
