Data Binding

Question

Hi I'm new to C# and want to specialize in WinForm apps and just started getting into Data Binding. In reading about multi tier applications where you have a presentation business and database tiers. Where does data binding fit in since data binding requires close ties to data sources? D oes the presentation tier access the database tier directly creating its own data cache then data bind to this data cache? Any light that you shed on this confusion would be much appreciated. Thank you

The business and data layer retrieve or update the data in a database for an ASP.NET application. It retrieve the data and bind it to the presentation layer. For more information study the following article: http://dotnetslackers.com/articles/aspnet/Three-Tier-Architecture-With-ASP-NET.aspx The presentation tier does not directly access the data tier. The presentation tier communicates with the data tier by way of the data access component in the middle tier.
