database?

I am trying to built a web database using the visual studio web developer 2005 express. client will be able to access the database in the intranet server. I found out that i can built a database using the web developer itself so what is the different from built database using the sql server? so where should i built my database in?I would suggest that you put the SQL Server database on your client's SQL Server. I have no experience with Visual Studio Web Developer Express but, if it's like Pro, there's a "App_Data" folder that allows you to create SQL Server databases (.mdf). You must have SQL Server 2005 express to do this but it's highly unlikely that your client will use SQL Server 2005 Express as their Production copy.
