2 VIEWpoint Provides access routes for direct, modem and national or international network users - 24 hours a day Conforms fully with the Prestel 'viewdata' display standards (software input/output filters can also be written for use with other display terminals) Ensures full data security with access being restricted by the use of unique user ID's and passwords - lower level access is strictly controlled by the use of Closed User Groups Enables the maintenance of multi-lingual versions of the database - with up to 27 languages being available simultaneously Provides local system utilities such as an interactive display screen editor and electronic mail Uses sophisticated communications interfaces to enable applications software to be resident locally or on the other side of the world Activity logging provides a full audit trail which would allow user billing and database usage statistics to be produced if required the communications system providing on-line data exchange - internationally

3 VIEWpoint VIEWpoint EASY ACCESS ‑ HIGH SECURITY The necessity to have up-to-date information available is a reality of modern business and VIEWpoint provides your users with access to selected data in a controlled, user-friendly way. Information is available, day or night, without any operator intervention being required and strict security ensures that only properly authorised users are able to see sensitive data. Access is possible for local users connected directly and (through the interfaces provided) for remote users connecting via modems or via the Ethernet LAN (using TCP/IP) or via X25 wide-area networks (including national and international packet-switched networks). Software packages are available to enable PC users to emulate the required 'viewdata' standard and even terminals of another standard could be accommodated by writing 'input/output filters' in software to mimic the correct keyboard and display characteristics. Filters for the DEC VT220 terminal and the French MINITEL terminal are already provided. Different language versions of display screens means that your valuable data can be presented easily for the benefit of a world-wide audience. The use of unique identification codes and associated passwords enable VIEWpoint to vet attempted connections and to prevent any unauthorised entry to the system. Having gained access, users are restricted to those parts of the database that are open to members of their 'Closed User Groups' (CUGs). There are up to 99,999 possible CUGs and any screen belongs to just one of these. A user, in turn, may be designated as a member of up to ten CUGs and have access to all screens belonging to these groups. VIEWpoint CUGs provide a very powerful and flexible means of controlling the information seen by different users.

4 VIEWpoint VIEWpoint TRULY USER-FRIENDLY No matter how useful the information, your users must be able to easily learn how to find and use it. VIEWpoint employs simple and consistent rules to ensure that the user does not get lost whilst navigating through the database. The database information is arranged as screens or 'frames' of information referenced by unique numbers. Users may access individual frames by entering the relevant number or the frames themselves may be 'menus' which will route through to the next frame depending on a choice made by the user. All standard Prestel commands are recognised whereby, for example, entering '#' will cause the next sequential frame to be displayed and '*#' will allow the user to 'step ‑ back' up to 15 frames. In addition to the frame number, a frame may have one or more separate 'keywords' associated with it which can be used to describe the subject material of the frame. If the user enters a subject keyword then (if the CUG rules permit) the frame with the matching keyword is displayed. During display of any menu frame the user may, subject to context, interrupt the display by entering the required menu option early ‑ thereby speeding database routing for more experienced users. VIEWpoint frames may be arranged into 'sequences' whereby selection of the next frame to display is automatic and the display will either wait for a specified time or for a user response before continuing. By employing timing with the 'frame overlay' feature (whereby only differences in succeeding frames are displayed) it is possible to generate animation sequences for added impact. The last frame of a sequence may also be made to refer back to the first ‑ thereby making a repeating 'carousel' of frames suitable for display purposes.

5 VIEWpoint VIEWpoint INTERNATIONAL COMMUNICATIONS GATEWAY Not all the information that you want users to see need be held on the local 'frame' database ‑ VIEWpoint provides you with a powerful 'gateway' through which the user can pass to gain access to software applications and remote databases. VIEWpoint enables two special types of frame to be created that allow the running of local utilities and both local and remote applications. A 'Gateway' frame invokes an external procedure which connects the user to another application which may be on the same computer or, via networking, a neighbouring computer or one on the other side of the world. VIEWpoint communicates with the application through a standard Applications Interface. An application may, for example, instruct that a specified frame be displayed to the user, request the user's terminal input or ask for other system ‑ held information (such as the user's name) to be displayed or forwarded to it. VIEWpoint also includes a unique Reference Store which an application may use to keep information to be used later. For example, an enquiry application may store the number of a part selected by the user that may then be referred to by an ordering application invoked later. A 'Data Collection' frame may be selected for display by an application invoked via a Gateway frame. This type of frame contains information concerning the location of display/input 'fields' and any input validation rules that apply to them. The application may then request that given data be displayed in particular field or that a field be completed locally by the user under VIEWpoint control. On completion of the input the data is then forwarded on to the application.

6 VIEWpoint VIEWpoint POWERFUL UTILITIES Behind the user environment lie the tools that make VIEWpoint such an easy and flexible system to use and control. Local utilities provide the system administrator with the ability to add information providers, to add system users and to monitor database usage - both by on-line enquiry and off-line audit trail reports. Information providers may add, change, delete or price data frames using the Frame Manager and amend screen displays by using the powerful Interactive Editor. The display editor is fully WYSIWYG and incorporates a block-move facility which enables frame to frame copying, within- frame copying and input/output to external files. Authorised VIEWpoint users may communicate with the administrator or with other users by means of a useful 'Electronic Mail' facility. Mail recipients can be notified of all unread messages they have received when they enter the system and mail - once read - may be deleted, forwarded or retained for future reference.
