Agenda 開發軟體工作的要求與挑戰 應用系統平台的特性 應用系統架構 新世代軟體系統的開發模型 Client/Server Architecture 3-Tiers Architecture .NET Application Architecture Service Oriented Architecture 新世代軟體系統的開發模型

3-Tiers Architecture User High Productivity Business Service Layer COM+/EnterpriseService User Database Server Presentation Layer IIS 6.0 ASP.NET High Productivity Very simple programming model VS.NET is good for ASP.NET High Performance & Scalable IIS 6.0 & Windows Server 2003 & SQL Server 2003 Clustering COM+ Clustering Secure Integrate with AD Encrypt Customized Logon info Reliable & High Availability IIS 6.0 & Windows Server 2003 & SQL Server 2003 Flexible to collaborate Little flexibility

3-Tiers Architecture with Web services Business Service Layer COM+/EnterpriseService User Database Server Smart client Other App Presentation Layer IIS 6.0 ASP.NET & Web services Now have some flexibility to collaborate with other Apps thru Web services Is a little complex due to Web services technology and 2 service interfaces Web services keep high Productivity using VS.NET & .NET Framework Built-in support for Asynchronous invocation Secure using WSE Scalable & Reliable using Windows Server 2003 / IIS 6.0

3-Tiers Architecture with Multiple Clients Windows Client Windows Client Smart Client Web Client SOAP Now we are facing some complex issues Define common data format between components More technology Remoting DCOM (avoid by using IIS Remoting) Serialization 4 service interfaces Duplicate code in user-interaction & Authentication & Authorization IIS Remoting Presentation Layer IIS 6.0 ASP.NET & Web services DCOM/ Remoting Business Service Layer COM+/EnterpriseService Database Server

Data access components .NET 應用程式架構 UI components UI process components Data access components Business workflows Business components Business entities Service agents Service interfaces Data sources Services UI Process Components deal with user interaction and navigation flow, installed at IIS for Web clients , or at client system for windows/PDA clients. Service Interfaces provide multiple communication end points to receive service requests, such as http/soap/msmq/remoting. (DCOM will not open for clients) Business Entities are data schema used by every components. Use Biztalk to handle Business workflows Service agents to outsiders
