VIRTEL WEB Modernization : modernization of the user interface.

VIRTEL WEB Modernization provides different modernization and development solutions for user interfaces, from simple 1-for-1 revamping to the creation of a truly dynamic Web interface. The application will then appear as a proper Web application while transactions and data continue to be held on the large-system platform.
The objective is to give users a new Web application interface that is easier to use, is perfectly adapted to their workstation and can also incorporate new functions if necessary.
These Web interfaces therefore help to reduce costs and the time required to train users while increasing their efficiency and productivity.

As a transactional communication monitor and HTTP server installed on the host, VIRTEL WEB can very simply use the technologies of the Web to modernize the interface of mainframe applications. In this case, the application server no longer functions within a distributed environment but operates directly on the mainframe.

The use of REST architecture style and the integration of AJAX concepts in the VIRTEL WEB Modernization module makes it possible to transform the applications of central sites into dynamic Web applications without the need to rewrite them.
This allows them to benefit from not only the latest technological advances but also from the dynamic possibilities of Web 2.0 (AJAX, JavaScript etc.).
This therefore increases the opportunities for upgrading and modernizing the user interface.

Use of these technologies in the VIRTEL WEB Modernization module means that companies are offered three major advantages:

• The mainframe application is preserved without necessarily modifying it.
• The interface is made more sophisticated without adversely affecting the performance of the application.
• JavaScript libraries are used, and in particular those written by YAHOO, GOOGLE, DOJO etc.

In order to achieve these objectives, in many cases it is enough to simply set the parameters of VIRTEL WEB Modernisation; this is very different from solutions that require integral redevelopment of applications.

The new Web page models are created with conventional Internet tools.
No mainframe/web cross-disciplinary expertise is required. Each team works within its usual environment. VIRTEL WEB is responsible for managing exchanges.

New screens (transaction logic, data, Web-adapted presentation) are controlled from the host and created using the models (HTML, XML etc.) stored in VIRTEL.

VIRTEL WEB Integration : Simplified integration of data and transactions within Web architectures.

VIRTEL WEB Integration provides a response to the integration concerns and requirements of companies. It is a simple method for integrating large-system applications into a service-oriented architecture (SOA). In order to achieve this, the VIRTEL WEB Integration module essentially makes use of HTTP and XML standards and is based on REST architecture style.

In order to facilitate SOA integration processes and initiatives, VIRTEL WEB Integration standardises exchanges between central site applications and other applications, both in terms of data and in terms of logical processes specific to the company.

VIRTEL WEB Integration is much more than a "passive" connector using the mainframe as a simple database:

• It allows interactive, real-time use of host applications from a Web application.
• To do this, it interprets XML flows and triggers transactions, the results of which are returned to the Web application.
• It can therefore be called up in a fully transparent fashion from any point of the company's information system.

This automatic conversion feature, both for incoming and outgoing data, makes VIRTEL WEB Integration a powerful asset in facilitating the dynamic integration of data and applications from a central site.
In fact, these data and applications can be invoked as a simple Web Service by any application or server.
VIRTEL WEB Integration is also fully compatible with integration platforms such as WebSphere Application Server, .Net, J2EE, Weblogic etc.

VIRTEL WEB Integration therefore fully standardises exchanges between host applications and other applications, both in terms of data and transactions, making mainframes fully-fledged citizens of the Web.

This concept allows companies to make the most of existing applications and facilitates their integration into a service-oriented architecture (SOA) or Web-oriented architecture (WOA).

Emergence of a New Web Application - As 3270 terminals are gradually phased out and replaced by Web browsers, Host and Web solutions can be combined to develop a brand new mainframe-based Web application that might have little left to do with the presentation and navigation of the original legacy 3270 application, except that it is built upon its time-proven functional and business processes, and benefits from the same mainframe strengths: reliability, availability, scalability, security, centralized management and support, etc.
