A data transmission dictionary is provided, which is adapted for use by a computer system for encoding, storing, or retrieving hierarchically related data transmission information. The dictionary is comprised of a group of one or more computer searchable definition trees relating to transmission information of the computer system. The trees are derived from a first definition group which includes characteristics of commands, replies or data usable by the computer system. The characteristics include structure and value properties and restrictions, if any, applying to the commands, replies or data. Each tree represents, respectively, a definition of a the command, reply or data to which it relates. Each tree includes a root node identified by name, e.g., a codepoint. The root node includes information describing the type of definition tree concerned (i.e., whether it relates to a command, reply or data), and may include one or more internal or terminal descendant nodes. These nodes represent components of the definition represented by the tree. The descendent nodes include level information describing the level of the node within its tree. The nodes may include attribute information, and may include value requirements relating to transmission information represented by the nodes.

A user inquiry facility and method are described for use in a computerized data processing system which provides for monitoring of conversations or information transmission between a user of the data processing system, during the execution of the user's program, and a communication partner (which could include a database or other facility) associated with the data processing system. Task progress tracing information is selected from the conversations and stored. The stored information is updated to keep it current with the progress of the task of the user's program. An instruction is provided by the facility or method which, when activated, by the user selects task progress tracing information from the stored information and after formatting it for readability is transmitted to the user-s display or terminal. The inquiry facility is independent of the successful operation of the user's program so that it can feedback information to the user about any failure in the program or in any communication paths used for the conversations.

Dictionary for encoding and retrieving hierarchical data processing

A method of creating a data transmission dictionary by deriving a group of one of more computer searchable definition trees from a first definition group of nodes defining portions of commands, replies, or data usable by a computer system, compacting each of the nodes by retaining only information necessary for the processing of data transmission streams according to the definition trees; assembling each definition tree by sequencing the compacted nodes in a linear form, starting with the root node of each of the definition trees, by placing information included in each compacted node in a resulting implemented dictionary; and by assembling each child node in the resulting implemented dictionary and assembling each of the child's child nodes in turn. The process of assembling a terminal node involves placing information included in the terminal node in the resulting implemented dictionary.

A system for processing diverse and non-diverse result sets is described. The system includes a client process in a client computer system that constructs a client process execution request identifying a stored procedure and specifying constraints on the quantity of response data that the client process is capable of handling. The client process execution request is transferred from the client process in the client computer system to a server process in a server computer system. The server process invokes the stored procedure identified by the client process execution request. Execution of the stored procedure results in the generation of answer set data for a plurality of diverse query result sets. Result set generators obtain answer set data for X of the query result sets, where X is defined by the constraints. The server process then generates an initial response containing, for each of the X query result sets, an amount of the obtained answer set data consistent with the constraints. The initial response is transferred from the server computer system to the client process in the client computer system. The client application is then able to access and process answer set data for the diverse result sets in any order.
