Web Based Terminal Emulation delivers traditional green screen terminal emulation in a browser. In environments where there are large numbers of transient users and in which managing the deployment of desktop software is a challenge, OASYS | Web Emulation offers the flexibility of accessing your host-based system from anywhere via a common browser. With support for most desktop emulator extensions such as file processing, pop-ups and other interoperable abilities, OASYS | Web Emulation offers a low cost way of distributing user access.

Dynamically Generated Responsive Web UI extends OASYS | Web with a framework that actively discovers screen flows and screen navigation to generate .NET screen definitions, producing fully responsive html and mobile interface without any changes in the backend application. OASYS | Web UI creates definitions that are easily customized, combined and enriched to deliver a new and more powerful user experience.


Web Application Development Framework (DesignBais) provides those firms needing new web-based application modules that desire to use existing MV developers in accomplishing an alternative, while continuing to develop legacy functionality. This structured configuration based framework rapidly develops new web-based capabilities against the existing legacy MV database.
