It will depend on wat the application is to do and who will access it. When developing a windows application, this will require the clients to have software installed onto there machine. But with a web application all they will need is a web browser.

With the windows app this software will include the sql native client as well as the .net framework.

One key issue is that if you decide on asp.net, you'll need to ask questions at www.asp.net and not here. Asking which way to go is fine, but once you decide, if it's ASP.NEt, I thought I'd get in early and point that out.

I'd go with a winforms app unless you wanted to expose functionality outside of your own network, on the web. b/c web dev is definately restricted compared to on the desktop, it's also more expensive ( each action involves generating new page instances, for example ).

You didn't say anything about your user interaction needs - If you are only transfer data from one side to the other you can write it as a windows service or even host it in SQL server itself.

Hi,

I guess you should elaborate more than this, however, selecting between winforms and webforms is not a big deal since code is reusable for both technologies, away from UI, however you need to answer these questions :

• What is the operating System of your users ( supposedly it will be Windows )
• Will you install .NET into users' machines or this will not be easy
• How are you going to handle system upgrades, in other words in case you change your system you will need to distribute the application to every PC again, you can expose it to a network drive to make life easier.
• The kind of UI you will require will be also considerable if it's reach and complex winforms are preferred than webforms.

Let me suggest one thing, I prefer you opt to 3 Tier design approach, finish you Data Access Layer ( DAL ) and your Business Logic Layer ( BLL ) , then you can work on WebForms or Winforms, furthermore you can develop one WebService that's using your DAL & BLL, and let any other platform users access the webservice.

Regards !
