摘要：There is a relationship between an application’s logical and physical architectures: The logical architecture always has at least as many tiers as the physical architecture. There may be more logical tiers than physical ones (because one physical tier can contain several logical tiers), but never fewer.

摘要：在分布式架构中，相关层在物理部署上实现分离，通过网络或跨进程调用远程对象或服务。在这种分布式架构中，需要定义有效的数据传输对象（Data Transfer Object, DTO）来实现层与层之间的数据传输。
因为远程调用需要跨越网络或进程，因此会比较慢。通过使用DTO，在单一远程调用中传输更多的数据信息，减少远程调用的次数，提高分布式调用的性能。

摘要：This article will focus on how to use a COM+ serviced component and some useful features of COM+ attributes. Then a practical COM+ application architecture will be depicted, which is more suitable to COM+ based enperise applications. At last a demo application is built in order to further verify the correctness and feasibility of my favorite COM+ application architecture.

摘要：.NET Enterprise Services 为企业应用程序提供重要的基础结构。COM+ 为企业环境中部署的组件编程模型提供服务结构。System.EnterpriseServices命名空间向 .NET 对象提供对 COM+ 服务的访问，COM+ 服务令 .NET Framework 对象更适用于企业应用程序。
服务组件（ServicedComponent）是一种使 COM+ 服务能够用于 .NET Framework的机制。实时 (JIT) 激活、同步、对象池、事务和共享的属性管理都是可以使用的熟知的 COM+ 服务。还有其他 COM+ 服务，如松耦合事件、排队组件 (QC) 和基于角色的安全性，可以使用这些服务来编写灵活的、基于 .Net Framework的应用程序。

摘要：As far as I’m aware, there are four different technologies, which can be used to build distributed applications in .Net platform. These technologies are .Net Remoting, Enterprise Services (COM+), Web Services and MSMQ (Microsoft's Message Queuing) respectively. It’s hard to say which one is better than other. Which one will be used to in a distributed application is depend on actual situation and requirements.
