Access to Legacy Applications and Data

By connecting your intranet to the Microsoft® Systems Network Architecture (SNA) network environment, you can gain access to the wealth of applications and data available on IBM platforms such as Multiple Virtual Storage (MVS) and OS/400 systems. Using Microsoft® SNA Server 4.0 SP2 as a data access server, you can readily develop scripts in Active Server Pages (ASP) that interoperate with legacy applications. This will allow you to process legacy data and distribute it across your intranet and over the Internet.

This section presents strategies for using Internet Information Services (IIS) 5.0 Web applications to access applications and data on IBM systems running in SNA environments—mainframes running MVS and AS/400 computers running OS/400. The strategies and scenarios in this section will help you use Microsoft development tools and production software packages in order to integrate legacy applications and data into IIS 5.0 Web applications.
