Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
Adopt distributed data of the present invention to unify catalog management method, at first will set up a memory device registration table on management equipment, this management equipment can be a PC, and portable machine also can be a workstation etc.This memory device registration table can be the group member registration table, forms the conjuncted system of group level.
The relevant information that comprises memory device in this registration table comprises type, title, internal number and the characteristic information of memory device.This memory device comprises the hardware storage device and the network storage equipment, and hardware storage device is such as present hard disk, flash disk, movable storage device etc., and the network storage equipment is such as mailbox, network memory etc.
As shown in table 1, be the instantiation of a registration table, comprised several memory devices in this registration table, comprise some memory devices of other PC that the hard disk of this machine is connected with CD and network.
| Device name | Device numbering | Device type | Apparatus characteristic |
| Office computer hard disk A | 0001 | Fixed memory device | ******** |
| Picture CD 200210 | 0002 | Optical disk medium | ******** |
| Friend C memory device | 0003 | Expansion storage medium | ******** |
Table 1
Wherein, expansion storage medium is exactly to point to the memory device registration table of cascade.
As shown in Figure 1, be a connection diagram of the present invention, as we can see from the figure, for registration table A, the equipment among the visit registration table B will use 002/003 such virtual drive number.On the basis of memory device registration table, set up a virtual directory then, each data is set to independent unique address.In the present invention, the address administration of virtual directory is very important, and we see a specific embodiment:
For example: data file test.txt is stored on the CD.The computer CD ROM of current use is the E dish.The device numbering of this CD in the memory device registration table is 0004.Therefore, the virtual address of this data file be 0004: folder test.txt, if actual address be E: folder the computing machine of the current use of test.txt., its CD-ROM drive is the F dish.Then actual address be F: folder test.txt. for data, its virtual address determines, and is irrelevant with current operation environment.But actual address and current operation environment are related.
At first, for the address data memory that current system can read, need convert virtual address to and just can be saved in the virtual directory.The method of conversion is the sequence number of the current memory device of inquiry in the virtual unit registration table, uses the driver section of the internal number replacement current address of this device registration.If the cascade system that forms according to above-mentioned group member registration table form then also need be set up unified cascade virtual directory.
For example: can be that A registers to B, set up member's registration table by B.For A distributes accession designation number.Like this, B can load the storage medium registration table of A, by Cascading Methods, the virtual directory address space of A is mapped to the address space of oneself.Therefore from certain angle, A also is a kind of memory device of broad sense.
Through after above-mentioned the setting, system uses this virtual directory that memory device is operated, and when system memory devices changes, situation of change is registered in the memory device registration table.The user can select to add this memory device registration table, also can select to withdraw from this memory device registration table, promptly deletes memory device from this registration table.
The present invention can set up the standard operation of network storage service by the network communication module, for example to the uploading of data, downloads, and duplicates etc., thereby the network storage equipment is equal to hardware storage device in operation.
As shown in Figure 2, be the present invention's schematic flow sheet the during data in the accessing storage device from virtual directory, as can be seen from the figure, comprise during visit:
At first read the virtual address of these data; This address be in the virtual directory of setting previously independently, unique address;
Specify the memory device title and the characteristic information of internal number correspondence then by the memory device registry query;
Determine whether current this equipment can visit, if can, then with virtual address translation to correct driver, visit normally; If cannot, then eject the loading equipemtn dialog box, suggestion loads this equipment.
The present invention is because the introducing of memory device registration table and the foundation of virtual directory, can manage based on the storage of data, rather than based on the storage administration of driver, can be under the situation that memory device does not have to load the browsing virtual catalogue, and carry out directory management; Because unified catalogue framework, unified address space can carry out system extension by cascade, promptly forms the virtual directory system in the network range, and the present invention simultaneously is with the integrated management of the hardware store and the network storage, for the user has brought very big convenience.
