The terminal device may be a variety of electronic devices having a display screen and supporting web browsing, including but not limited to smartphones, tablets, laptop and desktop computers, and the like.
The server may be a server for data management. Such as a server that provides data management for the AI platform.
When using the AI platform, the user creates a number of data sets (datasets) according to the traffic demand. The server may perform data management on these data sets.
The data management method provided by the embodiment of the present disclosure is described in detail below. Referring to fig. 2, fig. 2 is a flowchart of a data management method according to an embodiment of the disclosure. The method is applied to data management, and the data management method provided by the embodiment of the disclosure can comprise the following steps.
Step 210, receiving a first file storage request, where the first file storage request includes a first target file and a target directory, and a file name of the first target file is a target file name.
According to the present disclosure, a first file storage request may be used to request a server to store a file. The first target file may be a file to be stored. The target directory may be a directory storing files.
Step 220, writing the first target file into the source file directory.
According to an embodiment of the present disclosure, a source file directory is a directory that actually stores files.
Step 230, creating a first flexible connection file in the target directory, wherein the first flexible connection file points to a first target file in the source file directory, and the file name of the first flexible connection file is the target file name.
According to the embodiment of the present disclosure, a file to be stored is not actually stored in a target directory, but is stored in a source file directory, a soft link file corresponding to the file is created in the target directory, and the file is pointed to, so that a user appears to have created the file in the target directory.
Step 240, a version identifier is allocated to the first target file and the first flexible connection file.
According to embodiments of the present disclosure, the version identification may be used to indicate the versions of the first target file and the first flexible connection file. It should be noted that the present disclosure is not limited to the type of version identification. Illustratively, in this embodiment, a version number may be used as the version identifier, where a higher version number indicates a higher version.
In the conventional data management method, each time a data set is created, a full copy of the data and a manual version record are associated, so that the problems of data expansion and derivatization are caused, more time and energy are required for users, and the data storage cost is exponentially increased.
According to an embodiment of the present disclosure, a target file to be stored is written into a source file directory, a flexible connection file pointing to the target file is created in the target directory, and then version identification is assigned to the target file and the flexible connection file. Therefore, the method can automatically create the data, realize the version management of the data in a soft connection mode, save the time and energy of users, improve the efficiency of the version management of the data assets and reduce the cost of data storage.
In addition, the data management method according to the embodiment of the present disclosure does not invade the original storage usage logic, and can quickly form flexible data version management capability through a small amount of development. And thus can be quickly integrated by third party platforms.
Illustratively, the data management method according to the embodiment of the present disclosure may be applied to an AI platform. Based on the above, the first target file can include, for example, a data set used by the AI platform, and version management of the data set is realized by adopting a soft connection mode, so that various versions can be quickly generated for the data set on the premise of not occupying excessive storage resources, and the method is convenient for different AI training scenes.
Alternatively, the version identification may be stored in meta-information of the first target file, for example. When the version identifier needs to be acquired, the version identifier can be acquired from meta information of the first target file. Illustratively, taking the Linux system as an example, the meta information of the file is included in the inode, based on which the version identification may be stored in the meta information included in the inode of the first target file.
Alternatively, the version identification of the file may be globally controlled, generating a unique version number for each version of the file, thereby ensuring data management consistency.
Alternatively, the user may query for the stored files. Based on this, the user may send a file query request to the server through the terminal device, and the file query request may include the target directory and the file name to be queried. And the server receives the file inquiry request, inquires the to-be-inquired soft connection file with the name of the to-be-inquired file name in the inquiry target directory, and outputs the to-be-inquired target file indicated by the to-be-inquired soft connection file.
Alternatively, the user may delete the file stored in the server. However, when the original file on which the flexible connection depends is deleted carelessly, all version connections allocated based on the original file cannot be used. In this embodiment, in order to prevent a user from deleting a file carelessly, when the user deletes a file of a certain version, the soft link file of the version is deleted, and the target file of the version is stored in the corresponding recycle bin directory, so that data cannot be deleted truly. Therefore, the problem of soft connection failure caused by misdeletion can be avoided.
Based on this, the user may send a first deletion request to the server through the terminal device, and the first deletion request may include the first file name to be deleted and the target directory. And the server receives the first deleting request, deletes the to-be-deleted soft connection file with the name of the first to-be-deleted file name in the target directory according to the first deleting request, and moves the to-be-recovered target file corresponding to the to-be-deleted soft connection file to the recovery station directory. Wherein the recycle bin directory can be set according to actual needs. In addition, in the case that the target file to be recycled has other soft link files except the soft link file to be deleted, the other soft link files are modified to point to the target file to be recycled in the recycle bin directory.
If the user wants to delete the file completely, the user can send a second deletion request to the server through the terminal device, so that the server deletes the target file in the recycle bin directory. Wherein the second delete request may include a second file name to be deleted and a recycle bin directory. The server receives a second delete request. And aiming at the target file to be deleted, the file name of which is the second file name to be deleted, in the recycle bin directory, if the target file to be deleted does not have soft connection dependence, deleting the target file to be deleted in the recycle bin directory. And if the target file to be deleted has soft connection dependency, displaying the deleting prompt information. The deletion prompt information can be used for prompting the user whether to truly delete the target file to be deleted, and the user can send a confirmation deletion instruction after confirmation. And the server receives a confirmation deleting instruction corresponding to the deleting prompt information. And then deleting the target file to be deleted in the recycle bin directory according to the confirmation deleting instruction. If the user does not send the confirmation deleting instruction, the server does not delete the target file to be deleted.
Alternatively, after the user deletes the soft link file in the target directory, the file having the same file name as the soft link file may be further stored. Based on the file, the user can send a second file storage request to the server through the terminal equipment, wherein the second file storage request comprises a second target file and a target directory, and the file name of the second target file is the first file name to be deleted. The server receives a second file storage request, writes a second target file into the source file directory, and creates a second flexible connection file in the target directory, wherein the second flexible connection file points to the second target file in the source file directory, and the file name of the second flexible connection file is the first file name to be deleted. If the original target file with the file name being the first file name to be deleted exists in the recycle bin directory, a new version identifier is allocated to the second target file, and the version indicated by the new version identifier is higher than the version indicated by the version identifier of the original target file. If the original target file with the file name of the first file name to be deleted does not exist in the recycle bin directory, any version identification can be allocated to the second target file. For example, in this embodiment, the initial version identifier may be preset, and based on this, in a case where there is no original target file with a file name of the first file name to be deleted in the recycle bin directory, the initial version identifier may be allocated to the second target file.
The data management method provided by the embodiments of the present disclosure is described in more detail below in conjunction with specific embodiments and fig. 3A-3C.

As shown in fig. 3A, the AI development platform intends to create a data set dataset v1 and add a target file a therein, based on which the AI development platform can send a file storage request to the server, the file storage request including the target file a and the target directory dataset v1. After the server receives the file storage request, a target file a is created in a root directory (source file directory): root/a. The Version number (Version) 111 is added to the file metadata information included in the inode of the target file a. For the target file a of version 111, its actual data is stored in block. For distinction, the target file a in block is hereinafter referred to as the a-111 file.
Fig. 3B is a schematic diagram of data management according to another embodiment of the present disclosure. As shown in fig. 3B, the server may create a dataset v1, in which a soft link file a is added, and a corresponding soft connection is established: dataset/v1/a- >/root/a.
If the user carelessly deletes/root/a, the version of/root/a is 111, the version is: the target files a-111 of 111 are stored in the corresponding recycle bin directory without actually deleting the data and affecting the flexible connection of the target files. If the user wants to delete the file completely, a delete function is provided in the recycle bin. When deleting the target file in the recycle bin, the user can firstly judge whether the target file has soft connection dependence. If so, a deletion prompt message is displayed to prompt the user whether to confirm the deletion. After the confirmation deleting instruction of the user is obtained, the file is deleted. If not, the target file can be deleted directly.
Fig. 3C is a schematic diagram of data management according to another embodiment of the present disclosure. As shown in fig. 3C, after the user deletes/root/a carelessly, the user cannot see/root/a, and if the user re-creates/root/a again later, the version is calculated globally, and if the target file of version 111 is found in the recycle bin, the creation version number is increased, for example verison:222, to the newly created/root/a. For distinction purposes, the target file a in block version 222 is hereinafter referred to as the a-222 file.
