This emulation software runs on the user workstation for connection to mainframes in Web-to-Host mode.

 User workstation
WMA users have quick, easy access to the company information system using their browser (ActiveX components or Java applet) or directly through Windows (Windows emulators).
WMA provides uniform emulation of terminals, comprising all emulation functions: screen, printer, file transfer, macro language, etc ...
Thanks to its user-friendly interface, WMA integrates perfectly with office automation workstations and Internet applications: adjustable toolbars, programmable keyboard, keyword management (hotspots), etc ...


 Centralized administration
The centralized administration of WMA (Windows server) provides for secured management of all users and communications services with central applications.
User profile management is based on Microsoft Active Directory or the Windows SAM database.
Managing the WMA installed base is simple: deployment and updates are automatic on user workstations (either integrated or using Microsoft MSI components).
Communications may be supervised and logged for statistical and invoicing purposes.
In addition, WMA administration can be learned quickly and easily.


 Network and security
Direct communications with the market’s main central sites:
Central systems: IBM S/390, Bull DPS 7x, 8x, 9x.
Departmental systems: IBM AS/400, UNIX, Bull DPS 6.
There are several security levels available, in two categories::

• Securing of exchanges between the client workstation and the WMA server, thanks to the identification of the client workstation and utilization of the HTTP protocol,
  
  
• Securing of exchanges between the client workstation and the central site to which it is connected, by means of the Winsurf Security Server (WSS) gateway or the Telnet SSL (Secure Socket Layer) protocols.

 Architecture
The WMA architecture is based on the Microsoft Internet Information Server (IIS) web server.
This client-server architecture ensures performance during load increases. The WMA Advanced option makes it possible to implement solutions with load distribution among several WMA servers and recovery following incidents.
This solid architecture provides for setting up lightweight clients (Citrix Metaframe, Microsoft Terminal Server, etc.).
The IIS web server is a product open to application integration with Active Server Pages (ASP).
The WMA data can be stored in external SQL databases.
