Excerpt from “System Architecture.” (Hardware Users' Guide)
Abcde’s open client-server architecture combines diverse LAN and mainframe systems over multiple platforms into a single, unified network. This architecture supports Windows 3.1x with Win32S, Windows 95, and Windows NT Workstation 3.51 or 4.0 on local area network (LAN) units, Virtual Storage Access Method (VSAM), and sequential databases, and both dialup and dedicated LAN to LAN and LAN to mainframe connections using TCP/IP, NetBEUI/NetBIOS, and LU6.2/APPC.
Third party software, pre9601 releases, and legacy systems can be incorporated into this architecture by means of scripts, which relate Abcde's application program interfaces to client, LAN, and host applications.
Abcde’s application program interfaces are graphical and scalable. Graphical user interfaces (GUIs) consist of windows and icons which are clicked with a mouse to issue commands to a computer. You can create and modify windows to match your company’s business applications, and the size of your system can be adjusted to fit your company’s business needs.
Each level of Abcde is protected by security features. Access is controlled by defining and monitoring each user’s rights to access and use system tools, and requests to the host are verified for validity before a response is sent. Both Abcde and third party security systems such as Resource Access Control Facility (RACF), Advanced Communications Function (ACF2), and NetSp are supported. Sensitive data are encrypted.
