I have been checking this sample application (I'm trying to use it in my first multi-tier application.<br>
I plan to use three layers (user interface, business logics and data access) implemented in Duwamish 3 and 3.5 versions.<br>
<br>
If somebody have checked it too I have some questions...<br>
<br>
-The application doesn't verify user access to the database. I need to access an Informix db that checks user access... Must I send the User and Password as parameters when calling every method between layers?<br>
-The data access layer in version 3.5 (MTS) uses only two methods, is that enough?<br>
-Is it ok to use SQL commands in business logics layer?<br>
-Is Duwamish' multi-tier approach in general a good methodology to use in real world applications?<br>
