Legacy applications as resources for new service oriented applications?

Investment in new business systems is today largely channeled into development of service oriented applications. Development takes place on Open Systems platforms in integrated development environments. The aim is to use object oriented development techniques to produce discrete, and hopefully reusable, components. There are two main development thrusts:

  • Microsoft Windows environment, COM, COM+ and now .NET
  • Java for vendor-independent cross-platform applications

Regardless of the environment, these new applications, in order to provide real business benefits, must be able to retrieve and update information stored in core business applications running on legacy mainframe systems. The developers need Application Programming Interfaces that give them access to the core business applications in a way that is compatible with their development environment.
