Net.Visual

Creating Web Applications for Legacy Systems

With Net.Visual, you get the fastest & most effective way possible to extend legacy information to your employees, business partners, and customers via the web. Net.Visual can deliver legacy applications re-engineered for the web in weeks or months.

Net.Visual allows companies to build access to your corporate data securely using many alternate interfaces, such as .NET, Web, VB, C++, Java and many more. The scope is limitless…

Twincentric provides tools and help for organisations to develop interfaces to their existing applications via Net.Visual, serving hundreds or even thousands of users on the Web. With Net.Visual you can turn years of inwardly facing IT development and systems into self service applications, orders that were once placed over the phone can now be placed straight on the web or even over a new WAP phone, without rewriting any new applications and still maintaining your secure interfaces to the back office environment Net.Visual is an incredibly fast way to integrate e-business requirements with host based legacy applications. Our Enterprise Application Integration (EAI) solution consists of server-side components and development tools that work together seamlessly, allowing the creation of easily accessible data objects from ANY green-screen host application.

NET.VISUAL TECHNICAL OVERVIEW

The Net.Visual solution comprises of 3 fundamental components, these are:

Net Visual Server

Net.Visual server is installed and runs as an NT (or Windows 2000) service on a central server and handles the connections for session and/or network connections between the host(s) and the client…

Net.Visual server is installed and runs as an NT (or Windows 2000) service on a central server and handles the connections for session and/or network connections between the host(s) and the client. The type of client connections supported by the Net.Visual server depends upon the additional Net.Visual 'modules' installed.

The Net.Visual Server runs as a free-threaded, multi-threaded C++ application or service, handling multiple connections to the host, managed via the Windows NT multitasking manager. Each thread (session) runs as an on-demand basis, taking no overhead inactive. The pre-emptive Task Manager ensures that long tasks running off a single thread do not interfere with other threads, so that in the event of heavy session loads from the host, Net.Visual Server continues to function normally with no hindrance to other sessions on the system.

Net.Visual Server allows administrators to pre-configure access to the hosts, minimising future user-configuration issues. All connections to the host applications, connectivity session and configuration issues are managed by the Net.Visual Server. To ensure that only authorised users are able to access Host sessions, Net.Visual Server uses COM to manage the communications between the Net.Visual server and the remote clients.

Net.Visual Pool Server is a Windows NT/2000 service that connects to the Net.Visual Server and acts as a Net.Visual Virtual Client. Using the information created by Pool Server you can create one mainframe relationship to many client relationships be they Web, Wap or Client Server. Using Net.Visual Pool Server allows you to minimise the number of live concurrent connections running on your legacy system and greatly enhance the performance of your Client application.

Net.Visual Workbench is an application that allows you to build a database of objects related to a specific host application. Workbench stores information regarding each screen and the fields available on that screen. The Database is the repository of information from which Web Pages are constructed. Once the Net.Visual WEB Server has been installed, IT personnel use the in-built Application Navigator to define their application requirements, essentially 'reading' and 'learning' each individual green screen. The process takes only a few minutes per screen. During the process, each page of the application is navigated and identified as a unique object. Areas of the page are highlighted and labeled (e.g. input fields, text fields, etc.) and this information is written to the Database along with associated information on the key sequences involved in navigating from screen to screen. Once the necessary information about each Host application has been written to the database, users can now draw upon that information to create Web pages. These pages can be as complex or as simple as required, and can contain fields and data from multiple green screens originating from one or more Host applications. There is no requirement for all applications to reside on the same Host or Host type.
