Summary
In this chapter, we examined how web applications inherently follow a 3-tier client-server model, and how a 1-tier architecture can be used for simple applications in ASP.NET. Then we learned how we can logically partition this basic 1-tier 1-layer architectural style into two sub-layers, using code-behind files. We also studied how declarative code-less programming using new Data Source Controls follows a single-layer style.
In a nutshell:
Classic inline coding should not be used unless absolutely necessary. One case supporting it would be a project that mixes classic ASP and ASP.NET, or a project already built using this style of coding.
Data Source Controls (except Object Data Source) are only good for small projects which will never need to be scaled up in the future. For commercial-level projects, it's very important to logically break the code into layers.
The code-behind style is much more flexible, object-oriented, and scalable for commercial projects. We can break these layers...
