Answer 1

Short answer... Yes.

Databases are meant to be shared by many different applications as well as many different types of applications.

For VB.net and ASP.NET (in the code behind), you can use the same code to access the database...

Using _conn as New SqlConnection(connectionString)
  'Do Stuff'
End Using

For databases to use for free, you can get MS SQL Express edition , Oracle XE , MySql , and a few others.

如果将数据访问层（DAL）编写为Web服务（或WCF应用程序），则ASP.NET站点和Winforms应用程序都可以调用DAL，并可以访问同一数据库中的相同数据。
