GUI Graphical user interface for AS/400 and mainframe legacy applications
Jacada GUI development gives users major benefits
While the power, security, and simplicity offered by host-centric computing has kept most mission-critical AS/400 and mainframe legacy applications running, these systems usually lack the most desired feature - a graphical user interface. For most users, a GUI offers easy access to the host, desktop and network integration, and an open computing interface.
The GUI or graphical user interface:
- Makes an application easier to learn and use, resulting in shorter application learning curves and lower training costs
- Reduces documentation needs and costs
- Provides flexibility, and empowers users to more efficiently accomplish their tasks
- Provides the capability to share host data with other desktop and network application software, and
- Encapsulates desktop logic to extend and enhance the legacy application.
