An office information system having a plurality of work stations connected via a network to mutually exchange electronic mails each includes a control information definition unit for defining control information representing what kind of processing can be performed on mails after reception, a processing log memory unit for storing log information of operations which have been performed on a received mail, a control unit for guiding a receiver by referring to both the control information and log information, a task tracking instruction unit for inquiring the processing status of mail, and a task tracking unit for reporting the status in response to such a tracking instruction. The system stores and interprets control information relating to the flow of an OA object on the network, which has been conventionally involved in the memory of an office worker, and guides the office worker to work to be done by the office worker. As a result, a chance for the OA object to stagnate at a certain location is reduced, and the circulation of OA objects on the network is totally improved.

A program data managing apparatus comprising memories for storing as program data a source code, technique data on a process for making the source code, and intention data on intention to make the source code; a link indicative of the mutual relationship between program data; a display for displaying the relationship between the program data using the link; a link provided to indicate the relationship between a newly developed source code and the original program data from which the new source code derives; and a display for displaying the source code developed stepwise by that link and the related program data.

Method of software development

A computer assisted learning support system includes a storage for storing therein blocks of the teaching material respectively assigned with teaching material identifiers, the blocks being attained by subdividing the teaching material according to contents thereof, and link information which represents by a pair of identifiers of a teaching material a relationship between blocks of the teaching material, a display for presenting, in a change-over manner, a screen image of the blocks of the teaching material and a screen image of the contents of the blocks of the teaching material and the link information of the blocks, an input device for inputting therefrom a selection item for one of the displayed blocks of the teaching material items in response to the display thereof and a selection item for one of the link information items in response to the presentation of the contents of the blocks and the link information, a unit responsive to the selection for the block of the teaching material for displaying the contents of the selected block and the link information thereof, and a unit responsive to the selection for the link information for displaying in accordance with the selected link information the contents of a different block of the teaching material and link information of the different block.

Computer assisted learning support system and processing method therefor

In knowledge translation of data base in an expert system which draws inference based on knowledge, a table for defining a correspondence relationship between the knowledge and the data base, data base/knowledge translator for reading data necessary for the inference directly from the data base by using the correspondence relation table and translating it to knowledge form, and knowledge/data base translator for translating the knowledge prepared by the inference to data base form by using the correspondence relation table and storing it are provided.
