Hello Greg,
From your post, my understanding on this issue is: you wonder the best
practice of data accessing behavior. If I'm off base, please feel free to
let me know.
As we know, there are a lot of practices/solutions to do the data access.
For instance,
(1) We can use ADO.NET
(
http://msdn2.microsoft.com/en-us/library/h43ks021(VS.71).aspx) to hard
code Insert/Update/Select commands
(2) We can use LINQ
(
http://msdn2.microsoft.com/en-us/netframework/aa904594.aspx) if .net 3.5
is available to the development/deployment environment.
(3) Enterprise Library
(
http://msdn2.microsoft.com/en-us/library/aa480453.aspx) is also a very
good library based on ADO.NET
(4) Subsonic (
http://www.codeplex.com/subsonic) can automatically generate
the data access layer of a project according to the database schema, so
that programmers can focus on the business logic.
(5) or we can also build our own data access layer by applying DAO design
pattern.
http://java.sun.com/blueprints/patterns/DAO.html
Etc.
All in all, there are a lot of good practices to do the data access. It is
really hard to tell which one is the best. It depends on the real situation
to choose the fittest solution. For instance, if the database has a lot of
tables, views, we may consider the solution (4) subsonic, which can
generate the data access codes automatically, and save a lot of time for
the developer. But if the data access involves a lot of cross-table
operations, I'd suggest (2) or (3) or (5).
