Abstract

A data storage or management method is provided which allows both a content object-based access and a file-based access. A first request for storing a content object in accordance with the processing of an application program executed in a host is sent to an object archive control functionality executed in the host, an intermediate server, or a storage apparatus. The object archive control functionality generates an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier, and a plurality of file names corresponding to a plurality of fields contained in the content object. The storage apparatus stores a directory having the directory name and the plurality of files having the plurality of file names in accordance with the second request.

Claims

1. An application data storing method on an information processing system, the method comprising:

sending a first request to store a content object including a first field containing a content data generated by the processing of an application program executed in a first computer and a second field containing an attribute information of the content data;

generating an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier in accordance with a predetermined rule, a first file name corresponding to an identification information of the first field in accordance with the predetermined rule, and a second file name corresponding to an identification information of the second field in accordance with the predetermined rule;

sending a second request to create a directory having the directory name, a first file in the directory having the first file name and in which the content data of the first field is included, a second file in the directory having the second file name and in which the attribute information of the second field is included, and a field list file in the directory related to the content object and in which a correspondence between the identification information of the first field and the first file name and a correspondence between the identification information of the second field and the second file name are included;

sending the object identifier to the first computer for the application program to designate for reference or update of the content data; and

in the directory, storing the first file, the second file, and the field list file in response to the second request.

2. An application data storing method according to claim 1,

wherein the predetermined rule includes a rule wherein the field name of the field contained in the content object is used as a file name and a rule wherein an object identifier of the content object is used as a directory name.

3. An application data storing method according to claim 1, further comprising:

sending a third request with designation of the object identifier for editing the content object in accordance with the processing of the application program executed in the first computer;

specifying the directory name and the field list file in accordance with the object identifier received in response to the first request and the rule;

sending a fourth request to specify the first file name and the second file name in accordance with the field list file to read out data stored in the first file and the second file; and

sending the data stored in the first file and the second file in response to the fourth request.

4. An application data storing method according to claim 1,

wherein the first file, the second file, and the field list file are stored in a storage system.

5. An application data storing method according to claim 4, further comprising:

sending, to a storage system, a third request with designation of the first file name or the second file name in accordance with the processing of a file application executed in a second computer; and

by the storage system, sending a designated file which is one of the first file and the second file to the second computer in response to the third request.

6. An application data storing method according to claim 5, further comprising:

by the storage system, storing a third file generated by the second computer in the storage system.

7. An application data storing method according to claim 6,

wherein the first file, the second file, and the field list file, stored in the storage system, are stored in a file system in which the third file is stored.

8. An application data storing method in an information processing system, comprising:

sending a first request for storing a content object in accordance with the processing of an application program executed in a first computer;

sending a second request with designation of an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier, and a plurality of file names corresponding to a plurality of fields contained in the content object to thereby designate the directory name and the plurality of file names; and

storing a directory having the directory name and a plurality of files having the plurality of file names in response to the second request.

9. An application data storing method according to Claim 8, wherein a storage destination of the directory and the plurality of files is a storage system.

10. An application data storing method according to claim 9, further comprising:

sending a third request with designation of one of the plurality of file names to the storage system in accordance with the processing of a file application executed in a second computer; and

by the storage system, sending a file which is one of the plurality of files, corresponding to the one of the plurality of file names, to the second computer in response to the third request.

11. An information processing system comprising:

a first computer having an application program, and

a program for sending a first request to the archive management computer to store a content object including a first field containing a content data generated by a processing of the application program and a second field containing an attribute information of the content data;

a storage system; and

an archive management computer coupled to the first computer and the storage system,

wherein the archive management computer has a program to generate an object identifier corresponding to the content object received in response to the first request, a directory name corresponding to the object identifier in accordance with a predetermined rule, a first file name corresponding to an identification information of the first field in accordance with the predetermined rule, and a second file name corresponding to an identification information of the second field in accordance with the predetermined rule,

wherein the archive management computer has a program to send a second request to the archive storage system to create a directory having the directory name, a first file having the first file name and in which the content data of the first field is contained in the directory, a second file having the second file name and in which the attribute information of the second field is contained in the directory, a field list file related to the content object and in which a correspondence between the identification information of the first field and the first file name and a correspondence between the identification information of the second field and the second file name are contained in the directory,

wherein the archive management computer has a program to send the object identifier to the first computer in order for the application program to designate for reference or update of the content data, and

wherein the archive storage system stores the first file, the second file, and the field list file in the directory in response to the second request.
