Database based data retrieval system

Abstract

The invention discloses a database based data retrieval system and belongs to the technical field of databases. The system comprises a multi-level retrieval module and a storage module. The multi-level retrieval module sequentially comprises a type retrieval module, an attribute retrieval module, a name retrieval module, a topic retrieval module and a content retrieval module. The type retrieval module is used for retrieving data of related types. The attribute retrieval module is used for retrieving data of related attributes. The name retrieval module is used for retrieving data of related names. The topic retrieval module is used for retrieving data accordant with topics from the related data retrieved by the type retrieval module, the attribute retrieval module and the name retrieval module. The content retrieval module is used for retrieving data of related content. The multi-level retrieval module is connected with the storage module for storing the retrieved data. The system has the beneficial effects that the data grading retrieval is realized, the data storage and calling efficiency is improved, and the database development difficulty is lowered.

Description

technical field [0001] The present invention relates to the field of database technology, and more specifically, relates to a data retrieval system based on a database. 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 ...

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
