MicroServices with OpenAPI, WCF - SOAP Web Services to Leverage Terminal Applications

Inventu Viewer+ is based on Decades of Experience

We have built generations of tools and runtimes that work with legacy screen-based applications and deliver the transactions run by those screens as callable code.

The Inventu Viewer+ approach uses repeatable actions that let you start with your most important functionality and build from there over time. Our advanced set of tools use screen-oriented components first, then generates our exclusive object-oriented logic that is in a proven framework that is production-ready and easily extended.

Works with Any Host and Any Client Application

Inventu Viewer+ supports a wide variety of terminal emulation protocols and the generated MicroServices / web services can be called by any modern connected application including .NET, Java, PHP, Python and even directly from web clients using javascript AJAX including popular frameworks such as jQuery.

With the addition of the OpenAPI with SWAGGER option, all modern Web Application frameworks such as Angular, VueJS and React (for example) can now be clients with fully functional generated client API classes/services

• IBM mainframe, AS400/iSeries/IBM i, UNIX/Linux, VAX/VMS and MultiValue systems are supported using TN3270, TN5250, VT100/220/320, ADDS-Viewpoint, Wyse 50/60 or SCO-ANSI terminal protocols.
• Robotic Process Automation - Exclusive Object-Oriented State-Based Logic Engine can Tackle the Most Complex Processing Challenges
• Open API / Web API - Introduced in 2018 - SWAGGER Compatible Callable Services
• Inventu ScreenAPI - Introduced in 2018 - Auto-generated Web API Read/Write/Navigate for all Screens in Your Project
• Angular, VueJS, React and Other frameworks all can consume the OpenAPI/SWAGGER MicroServices
• WCF 3-Way Web Services -- WCF option Generates Web Services, REST-XML and REST-JSON options.
• Call methods directly from web clients using jQuery AJAX/JSON requests. Each web service includes sample jQuery web pages for calling and integrating (if you prefer another Javascript framework, the calls are easily integrated as AJAX/JSON).
• Safer and less complicated implementation of data entry and update transactions over direct database access techniques
• Automate Database synchronization and replication with SQL Server, Oracle and other non-mainframe databases
• Integrate host data with mobile, portals, BPM software, dashboards, and other platforms

Non-Proprietary Production Applications

Inventu Viewer+ Web Services are generated, fully editable Visual Studio solutions that are published as standard IIS applications (We recommend Windows Server 2016 or Windows Server 2019). Our code is generated in production-ready c# classes that are running today on customer servers worldwide. The logic is designed for easy modification without breaking continuous productivity brought with new code generation cycles.

• Your web service code is insulated from any future changes to the host screens. The Inventu Viewer+ screen recording, modeling and screen I/O assembly generator guarantee it.
• A long-term solution; Compatibility with the latest Web Application Frameworks such as VueJS and Angular, along with Full integration with Microsoft Server technology and tools means no wasted development and no dead-end tools
• Logic for transactions is in object-oriented, state-based methods--tweaks to logic can be focused with minimal impacts on the rest of the application
• All data reads/writes and navigation between screens is in automated, generated code avoiding tedious error-prone manual coding
