Abstract

CCP data as common data, which can be utilized by a plurality of users or applications, are stored in a CCP buffer in units of data types (format IDs). More specifically, the CCP buffer stores one CCP data per format ID. Upon reception of a request for CCP data from an application, the system analyzes this request to acquire the format ID of the CCP data requested by the application. The system searches CCP data having a format ID coinciding with the requested format ID from data management information of CCP data. The system passes the searched CCP data to the application, and ends processing. In this manner, CCP data can be stored in correspondence with a plurality of data types, and required CCP data can be easily selected by using its format ID. Therefore, operability with respect to common data can be improved, and work efficiency of users can be improved.

9. The method according to claim 7, wherein the data each have format information representing a data format of those data, each application program has ability information representing a data format processable by that application, and said judging step includes judging whether or not an application program found in said searching step is capable of processing data corresponding to the data icon designated in said designation step, based on the format information and the ability information.

10. A data management method, comprising:

a display step of displaying one or more application icons each of which corresponds to an application program and one or more data icons each of which corresponds to data created by one or more application programs;

a designation step of designating a data icon displayed in said display step;

a searching step of searching for an application program;

a judging step of judging whether or not an application program is capable of processing data corresponding to the data icon designated in said designation step; and

a display control step of changing an application icon corresponding to the application program judged in said judging step as being capable of processing the data so that the application icon is distinguishable from other application icons.

11. The method according to claim 10, wherein said display control step includes displaying the application icon corresponding to the application program judged in said judging step as being capable of processing the data, by highlight-displaying.

12. The method according to claim 10, wherein the data each have format information representing a data format of those data, each application program has ability information representing a data format processable by that application, and said judging step includes judging whether or not an application program found in said searching step is capable of processing data corresponding to the data icon designated in said designation step, based on the format information and the ability information.
