Product information-based data retrieval system

Abstract

The invention discloses a product information-based data retrieval system, and belongs to the technical field of databases. The system comprises a user module, a pre-processing module, a retrieval module and a storage module, wherein the retrieval module comprises a retrieval category module, a retrieval name module and a retrieval content module in sequence; the retrieval category module is used for retrieving the data of related categories; the retrieval name module is used for retrieving the data of related names; the retrieval content module is used for retrieving the data of related contents; the storage module is used for storing the data of product information; the pre-processing module is used for carrying out further pre-processing analysis on the product information so as to facilitate the data retrieval of the retrieval module; the user module and the retrieval module are respectively connected with the pre-processing module; and the retrieval module is connected with the storage module. The system disclosed in the invention has the beneficial effects of realizing the grading retrieval of the data, improving the storage rate and calling efficiency of the data and reducing the development difficulty of the databases.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a data retrieval system based on product information. Background technique [0002] With the rapid development of computer network technology, the application of switch devices is becoming more and more extensive, the functions supported by switches are becoming more and more powerful, and the configuration information is becoming more and more complex. Therefore, the storage and management of all configuration data on switches is also proposed. higher requirements. [0003] Currently, the configuration data to be saved on the switch is generally organized and stored in a binary format in a hardware NVRAM (Non-Volatile Random Access Memory, non-volatile random access memory) device. In the existing switch system, the management of configuration data is usually taken care of by each functional module, and the data forms of each definition are not uniform, which easily leads to ...

AI Technical Summary

Problems solved by technology

The management of configuration data in the existing switch system is usually the responsibility of each functional module, and the data format of each definition is not uniform, which may easily cause configuration redundancy

For example, one of the functional modules needs to save each port and the switch status information corresponding to the port, and a set of one-to-one corresponding data formats can be defined to store this configuration, while the other functional module also needs to save each port and the corresponding other Another set of attribute information, so another set of configuration is saved according to the format defined by the functional module itself, which will easily cause inconsistent configuration data, unreasonable structure, and redundancy, and waste storage space at the same time

At the same time, the upper-layer application is responsible for managing the reading and writing of the existing configuration, and the configuration that needs to be saved by the defined module is read and written, which brings great inconvenience to the upper-layer application developers, because the upper-layer application developers

[0004] When parsing configuration data, you need to know in what form and where a specific configuration is stored, etc., especially when it comes to the interaction with related configuration items of other modules, you also need to consider the configuration organization format of other modules , which increases the difficulty of developing
