Legacy Interfaces to Systems of Record

Many systems are record are stored on enterprise systems such as the IBM z Mainframe, or IBM i (AS/400). These systems date back to the time of punch cards, and so do many of the applications running on them. While both of these systems have kept up with industry standards and API’s (think CICS web services), there are still applications that are heavily in use which have 3270 or 5250 telnet interface. These legacy green screen interfaces pose several problems for an organization:

  • They are difficult for new employees to learn
  • Limited screen real estate prevent display of the optimal flow of data
  • Tightly linked to the underlying business logic, making separating them very tedious and time consuming


Refresh your existing assets with a rich web interface

We can reface your legacy green screen applications with a rich, responsive web interface. We do this without accessing your source code. In fact we don’t touch or make ANY changes to the existing application; you can still use the application via the terminal. Using IBM HATS we dynamically interpret the 3270/5250 data stream, creating objects on the fly, which we manipulate into web content.

Here are some of the benefits of the solution:

  • Reduce training time by as much as 75%
  • Surface intranet based applications to the internet for customers to access
  • Integrate legacy applications with other in-house applications.
  • Provide drop downs, checkboxes, radio buttons to limit data entry errors
  • Validate in the browser to avoid garbage data
  • Extend the life of an application by years
