Abstract

An architecture for the implementation of an information utility for accessing information and executing transactions on an interactive basis between Videotex databases and individual end user terminals, some or all of which may be remotely located with respect to each other. The utility may be associated with a Videotex Application Network (VAN) and includes a combination of distributed, semiautonomous Operations Nodes (ONs), each characterized by (1) one or more affiliated users, (2) the inclusion of some form of database, and (3) one or more customized application programs, and each is also capable of "standalone" operation. Each database comprises pages of control information and displayable data. Each node comprises a directory of databases at other nodes.

13. A system as in claim 1 wherein said first database means comprises a database directory of said first operational node.

14. A system as in claim 1 wherein said first database means further comprises pageset means for organizing said page means in a scroll sequence.

15. A system as in claim 14 further comprising scroll means for accessing said page means in their sequence order within a pageset means for display on said terminal means.

16. A system as in claim 1 further comprising find means for accessing said page means directly from within said database means.

17. A system as in claim 1 further comprising mark means for marking said page means being displayed on said terminal means for later access.

18. A system as in claim 1 further comprising recall means for recalling said page means that was marked for later access.

19. A system as in claim 1 further comprising defining means for identifying said page means being displayed by a synonym for later access.

20. A system as in claim 1 wherein said first application program means comprises means for adding information to said page means after being selected for and prior to display.

21. A system as in claim 1 further comprising first check means for accessing said first database means and second check means for accessing said page means.

22. A system as in claim 1 wherein said first application program means comprises means for invoking and executing a program in response to a user selection through said terminal means.
