Abstract: An information processing system includes a monitoring program starting unit and a protection target program monitoring unit. When a protection target program to be protected is started, the monitoring program starting unit starts a monitoring program that monitors the protection target program. The protection target program monitoring unit monitors the protection target program by the monitoring program.

Abstract: An information processing system includes a monitoring program starting unit and a protection target program monitoring unit. When a protection target program to be protected is started, the monitoring program starting unit starts a monitoring program that monitors the protection target program. The protection target program monitoring unit monitors the protection target program by the monitoring program.

Abstract: An execution program including encoded code portions is executed on an operating system inhibiting the rewriting of program code area. The execution program includes encoding target code and code not encoded. Immediately before executing the encoding target code, the encoding targets code is decoded and relocation processing is performed for the encoding target code. Immediately after starting the encoding target code, the encoding target code is not decoded. When the program execution has proceeded to the stage in which to execute the encoding target code, an area for decoding the encoding target code is allocated, and then the encoding target code is decoded within the area and thus relocated.

Abstract: A document data processor system includes means for evaluating a user's impression of a layout of a document, and means for storing the evaluation information. The system also includes means for storing document design knowledge regarding the layout of multiple standard documents. The system allows a user to create a new document based on the stored document design knowledge and the stored evaluation information so that new documents are created in accordance with user's desires, as reflected by previous document evaluations. In addition, a draft document that is being created may be re-formatted based on a user's evaluation of the draft.

Abstract: A data management system which enables a user to flexibly make corresponding relation between data stored in a existing database, and a data file and a program for processing the data file, is disclosed. A user register in advance corresponding relation between a data unit stored in a existing database, and a data file and a program for processing the data file, both of which exist outside of said first database. After the retrieval of the data unit from the existing database, if the corresponding relation for the retrieved data unit is registered, the program related to the data unit is activated for processing the related data file in response to the user's instruction.

Abstract: A data unit group handling apparatus which handles a file system for storing a plurality of files defined by different kind of file formats, and at least one of the files is a data unit group which is defined by a predetermined file format, includes data units and can be located in any location in the file system. In the apparatus, at least one data unit group is retrieved from the file system in accordance with the file format, a selection instruction is received from a user to select at least one of the data unit group from the retrieved at least one data unit group, retrieval condition to retrieve at least one data unit is also received, and at least one of the data unit matching to the received retrieval condition from the at least one of the data unit group which is selected in accordance with the received selection instruction.
