Problems solved by technology

However, there will be some problems in this way. For example, it will be more difficult to obtain the associated information between MRL and agricultural products or store the associated information; on the other hand, the reading speed of the disk is relatively slow. , this problem is particularly

Embodiment Construction

[0077] Below in conjunction with accompanying drawing, further describe the present invention through embodiment, but do not limit the scope of the present invention in any way.

[0078] The invention provides a data association access method based on a three-dimensional table structure, and applies it to a system for managing MRL standard data in multiple countries or regions, which can greatly improve the efficiency of system access data.

[0079] The method of the present invention can be applied to the access function of the management system under the universal situation. Generally, the management system under the universal situation includes application programs and databases, and the hardware part includes storage devices. The application program is a system implemented by programming, which is used to receive user instructions and convert the instructions into relevant machine language and operations; the database is a warehouse used to organize, store and manage data, ...

Abstract

The invention discloses a data associative access method based on a three-dimensional table structure and an application. The method is used for achieving high-efficiency data access operation of a management system. According to the data associative access method, two storage spaces, namely a low level storage space and a high level storage space, are designed in addition to a conventional storage space for storage equipment of the management system, and used for storing a Hash table and calculating mapping data by using a Hash function; when a user sends an inquiry request, the data associative access method resolves the request sent by the user, and achieves inquiry reading operation or inquiry storage operation via associative operation of multiple database tables; and high-efficiency data access of the management system is achieved. The method is applied to a pesticide residue data management system, achieves effective management of pesticide information, agricultural product information, and data of multiple associative tables of MRL (maximum residue limit) standard information of multiple countries or regions, and greatly increases an access speed.

Description

technical field [0001] The present invention relates to data storage and reading technology, in particular to a data association access method based on a three-dimensional table structure, and is applied to the association, storage and read. Background technique [0002] With the construction of an information society, the problem of big data storage and reading has also been exposed. In existing technologies, relational databases are often used to store information. When using relational database SQL (Structured Query Language) to query a large amount of data, the amount of data in the result table is large, the system responds too slowly, and even causes the system to crash. When using multiple database tables to store different types of data, it is necessary to design and implement the associated operations of the database tables. [0003] Data access speed affects system performance to a certain extent. Using the Hash mapping method can improve the efficiency of syst...
