Embodiment 1

[0041] The embodiment of the present invention provides an image data management system based on database technology and layered data, such as figure 1 As shown, it includes a client device, a data query module, a data operation module and a data storage module, and the client device is connected to the data storage module through the data query module and the data operation module respectively.

[0042] Among them, the client device is used to provide users with visualized data query and data operation results; the data query module is used to query the image data in the data storage module; the data operation module is used to store the image data in the data storage module , delete or modify operations; the data storage module includes a database table unit and a layered data file storage unit, the database table unit is used to store the metadata information of the image data and the location information of the image in the layered data file, and the layered data file is st...

Embodiment 2

[0054] The embodiment of the present invention provides an image data management method based on database technology and layered data, such as figure 2 As shown, the following steps S1-S3 are included:

[0055] S1. Build a database table unit and a layered data file storage unit to store image data layeredly.

[0056] like image 3 As shown, step S1 includes the following sub-steps S11-S15:

[0057] S11. Design metadata content and construct a database table unit, and store metadata in the database table unit.

[0058] According to the system requirements, the background environment of the image information and the query conditions in the use scene, design the metadata content, and build a table in the database to build a database table unit. The database table unit should also include: image data storage path, data group name , data set name and other hierarchical data file structure information and mapping flag information.

[0059] In the embodiment of the present inve...

Abstract

The invention discloses an image data management system and method based on database technology and layered data. Combining the database technology and layered data format, the problems of low efficiency and low safety factor in the current image data management are solved. Support multiple metadata, easy retrieval, flexible and intuitive image data management system. The invention uses the database table unit to store metadata, which is convenient, flexible and intuitive to retrieve, and supports multiple data formats. The present invention uses a layered data format to store file data, and users cannot directly access and view data through the operating system. After a large amount of image data is stored in a layered data structure, it is usually very large and difficult to be directly copied or deleted, which reduces the cost of data encryption and also The risk of data leakage and accidental deletion is reduced. In the layered data format of the present invention, various data can be stored simultaneously, the expansibility is extremely strong, the data is more concise, and the ability of system data management is enhanced.

Description

technical field [0001] The invention belongs to the technical field of data management, and in particular relates to the design of an image data management system and method based on database technology and layered data. Background technique [0002] In the current general data management system, there are two storage methods for image data: [0003] 1. Store image data in binary format, bitmap format or XML format in a relational or non-relational database. [0004] 2. Combining the database and the file management system, store the image path in the database, and when reading the file, query the path and call the image in the file system. [0005] Among them, method 1 is due to the large image data and the size of the database table is greatly enhanced, which reduces the query speed. Method 2 directly stores images in the file system of the operating system, which is prone to image loss or invalid paths due to folder name changes , for all users, the data is directly vis...
