Embodiment 1

[0078] In the first embodiment, all directory structures are composed into a directory file and the directory file is uploaded, see Figure 4 As shown, the method specifically includes steps 401-408:

[0079] Step 401: After receiving an instruction to upload a target folder, traverse the target folder to determine all file data in the target folder.

[0080] Wherein, the file data is a file directory or file in the target folder.

[0081] Step 402: Determine the directory information of the file data.

[0082] Wherein, the directory information includes one or more of the name of the file data, the parent node of the file data, and the type of the file data.

[0083] Step 403: Generate a directory structure according to the directory information, where the directory structure is structured data for marking the storage location of the file data.

[0084] Step 404: Repeat the step of establishing a relevant directory structure according to the file data until all file data h...

Abstract

The invention discloses a method and device for establishing a directory structure of a database. The method comprises the following steps of: after a command of uploading a target folder is received, traversing the target folder to determine all the file data in the target folder, wherein the file data indicates file directories or files in the target folder; establishing a related directory structure according to the file data, wherein the directory structure is used for marking storage positions of the file data; and uploading the directory structure and the files in the target folder. According to the method, the target folder can be expressed through the directory structure and all the files in the target folder, and the aim of storing the target folder can be realized, so that the storage space of the database is saved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and device for establishing a database directory structure. Background technique [0002] With the development of computer science and multimedia, in the development of products with database systems such as computer networks, mobile computers, mobile phones, and satellite navigators, the database must not only deal with simple structured data, but also often deal with a large number of complex non- Structured data, such as graphics, sound files, or large text files, etc., these complex unstructured data are often accessed in the database in units of files. In addition to the database storage of a single file, in the application, a collection of multiple files organized by the file system according to a certain directory structure (called a file set) needs to be stored in the database as a whole. [0003] In many application systems in various fields at present, it...
