Problems solved by technology

This design method is in line with the software design and can make the software more flexible, but there will be problems in the process of data query; because the above information is stored in different tables, it is necessary to associate all information through the method of table association
The association will cause a rapid increase in the amount of resulting data, and the faster the Cartesian product increases
Therefore, in some high-frequency query services, this method may not meet the concurrency requirements of the system, or the response efficiency is very low

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] Such as Figure 1-3 As shown, a method for fast retrieval and acquisition of data characteristics based on attribute matching, specifically includes the following steps:

[0043] Step 1. If figure 1 Build a model for attribute matching.

[0044] 1-1. Classify m attributes, specifically: classify two or more mutually exclusive attributes among the m attributes; if one or more attributes do not have mutually exclusive two or more attributes If there are multiple attributes, a single attribute is assigned to one category, for example, the m attributes are divided into C 0 ,C 1 ,C 2 ,C 3 …C c-1 Such several categories, we call these categories as attribute categories. The set formed by m attributes is called the total set of attributes.

[0045] 1-2. Number m attributes, numbering principle: attribute numbers in the same class are adjacent, ...

Abstract

The invention discloses a method for carrying out rapid retrieval and acquiring data features on the basis of attribute matching. The method comprises the steps of: S1, setting up an attribute matching model; and S2, based on the attribute matching model, carrying out rapid retrieval. The method disclosed by the invention is a method abstracted out on the basis of an item of acquiring a user with a certain attribute. The method uses rapid operation and rapid selection of a memory and a multi-order caching technology. By using the method, a matching result is rapidly acquired, and reusability of the matching result is reinforced. A memory database is introduced to carry out caching on retrieval data and memory data is used for carrying out calculation of an intermediate result, so that the bottleneck of a conventional retrieval method on the aspect of a hard disk is shortened, and a data output speed and volume are improved.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and relates to a method for quickly searching and acquiring data features based on attribute matching. Background technique [0002] The current business system is more and more responsible, but in the process of software design, everyone uses the object-oriented method to design and develop the platform, such as the personal information in the school or company management system may have multiple tables of information. At the same time, these information are stored in separate tables. This design method is in line with the software design and can make the software more flexible, but there will be problems in the process of data query; because the above information is stored in different tables, it is necessary to associate all information through the method of table association . The association will cause a rapid increase in the amount of resulting data, and the faster the Carte...
