    • PURPOSE:To improve the user interface and the performance of a control system for CAD graphic data base by extracting an bloc the data related with each other according to the relation between data. CONSTITUTION:The data defining information, the inter-data relation defining information, and the data batch operation defining information produced from said two defining information are stored in a memory. Then data are processed when the data are operated based on the contents of those three types of information. Thus a CAD system can perform an block each time the retrieval of a series of related data groups which are frequency carried out in the system. As a result, the access processing is simplified for the graphic data in the CAD system. Furthermore the data processing time is shortened owing to decrease of the access frequency of the graphic data.

    • PURPOSE:To attain the control of graphic data with confirmation of the detailed structure of the graphic data by executing the requested processing with reference to the structure defining information on the graphic data developed into a main memory. CONSTITUTION:A data control subsystem 3 in a main memory 1 executes the overall initialization processing of a graphic data base control system and gives a request to a user of a graphic terminal 6 to supply the name of a user program 7 to be executed. When the program 7 is designated, the system 3 retrieves the graphic data structure defining information 51 on the program 7 out of a data base 5 and develops it into the memory 1. This developed information 51 is kept resident in the memory 1 until the execution is through with the program 7. Then the system 3 starts the program 7 through a user program execution control part 31 and then repeats to wait for the processing request for graphic data given from the program 7 and to execute the request processing until the end of execution of the program 7.

    • PROBLEM TO BE SOLVED: To solve the problem that when delivery of purchased digital content fails, it is required to input purchaser information again for retrying a purchase process or to check purchase records for preventing duplicate payment while there are limitations on the number of delivery retries and a repurchase period. SOLUTION: A digital content delivery method generates a digital content personal use condition on the basis of a digital content use condition 104 and gives the digital content personal use condition to a purchaser when an electronic mall server 110 sales digital content 101. As for repurchase when the delivery of the digital content 101 fails, if the digital content personal use condition given when the digital content 101 is purchased is valid, the digital content 101 is redelivered without collecting a digital content value 103 again.

    • 要解决的问题:为了解决在购买的数字内容的交付失败的情况下,需要再次输入购买者信息以重试购买过程或检查购买记录以防止重复付款,而数量有限制 的交货重试和回购期。 解决方案:数字内容传送方法基于数​​字内容使用条件104生成数字内容个人使用条件,并且当电子商城服务器110销售数字内容101时,将数字内容个人使用条件提供给购买者。 为了在数字内容101的传送失败时回购,如果在购买数字内容101时给出的数字内容个人使用条件有效,则重新发送数字内容101而不再次收集数字内容值103。 版权所有(C)2009,JPO&INPIT
