Abstract: For access to material via the World Wide Web Internet service, Web page URLS are stored as attribute-values of directory objects and Web page hyperlinks to those directory objects are provided together with access logic responsive to the hyperlinks for retrieving 230 the URLS for use by a client. This indirect access to Web pages via hyperlinks to directories has significant advantages for Web page organisation and facilitates more flexible methods of Web page access than the known use of hyperlinks which include URLS pointing directly to the target Web pages.

Abstract: A programmable workstation for collaborative working in a network comprises a conventional operating system and a network control program layer. Additionally, the workstation includes a collaborative application support subsystem for interfacing with application programs. The subsystem is responsive to predetermined application program calls to create a logical network model of a collaborative environment. The model comprises sharing sets of application programs, which share data and resources across nodes and logical dedicated data channels connecting members of the sharing set. The subsystem cooperates with the network layer to establish the physical links necessary to implement the model in a physical network, transparently to the application program.

Abstract: A data communications apparatus connected to a network through which datagrams flow from the data communications apparatus to at least one other data communications apparatus also connected to the network, the apparatus having: a means for receiving data which is to be transmitted over the network, such data being broken up into data records; and a means for packing the data records into datagrams for transmission over the network, including a means for assigning data records to datagrams; wherein the means for packing takes the data records out of sequential order when assigning data records to datagrams.

Abstract: A data retrieval system stores a plurality of objects having a multi-level hierarchical relationship, each object having a respective parent and a set of children. The system stores one or more base tables, the or each base table comprising a respective set of attributes associated with a sub-set of objects in the system, and generates for the, or each, base table a respective complementary table, the or each complementary table comprising a set of attributes excluding the attributes of the associated base table. The system further includes an expression optimiser adapted to interpret a query comprising an expression including one or more operations, each operation having a respective operator and one or more associated operands. The optimiser tracks a number of objects associated with the or each operation and any attributes associated with the operation; and re-formulates the expression accordingly. The system enables optimisation of relational expressions, by transforming a supplied expression into one which is faster (less resource consuming) to evaluate. It eliminates unnecessary operations, and possibly re-orders others, this results in the elimination of certain base relations from an expression, where possible.

Abstract: A programmable workstation for collaborative working in a network comprises a conventional operating system and network control layer for controlling physical routing of data between nodes. A collaborative application subsystem which interfaces with conventional telephones is responsive to a predetermined call from a collaboration call manager to establish the call manager at the node to handle incoming events which are not specific to any application program instances at the node.
