Problems solved by technology

However, when the number of data records increases to a certain extent, frequent reading and writing of the database will consume a large amount of I / O (input / output) resources, resulting in low overall analysis efficiency
In addition, when there are high requirements for timeliness in business, such as real-time risk monitoring of bank transactions, statistical results cannot be returned in time

Embodiment Construction

[0025] In order to facilitate the understanding of various aspects, features and advantages of the technical solutions of the present invention, the present invention will be specifically described below in conjunction with the accompanying drawings. It should be understood that the various implementations described below are only for illustration, rather than limiting the protection scope of the present invention.

[0026] Firstly, the names or terms that may be involved in the present invention are explained.

[0027] Dimension: A common property of structured data objects. For example, the dimensions of bank transaction data include customer, transaction IP, transaction date, etc.

[0028] Context relationship: the relationship between structured data objects in two dimensions. For example, bank transaction data can generate relationships based on customer dimension and time series dimension, and relationship can be generated based on transaction IP dimension and time ser...

Abstract

The invention discloses a memory-based data processing method and device. The method comprises the following steps: writing structural data which comprises a plurality of data records into a first memory area and establishing a plurality of chain tables according to the structural data, wherein pointers which are used for accessing to data elements belonging to different data records, belonging to a same dimensionality and having a same value are stored in data fields of the chain tables; and searching the data elements in the structural data through the chain tables and carrying out data processing according to a statistical index and a calculation method stored in a second memory area. By adopting the memory-based data processing method and device, the I/O overhead can be greatly reduced, the data processing efficiency can be improved and the statistical result can be returned in time.

Description

technical field [0001] The present invention relates to the field of data processing, and more specifically, to a memory-based data processing method and device. Background technique [0002] With the development of information technology, statistical analysis of large amounts of data can be used to help decision-making in many fields. For example, in the field of bank risk monitoring, it is possible to judge whether the customer's transaction is risky by analyzing each transaction behavior of the customer and a certain context related to the transaction, and to decide whether to take action on the customer's transaction. control measures. Different from other data statistical analysis requirements, bank risk monitoring is characterized by the requirement to quickly return the analysis results of customer transactions within a short period of time (for example, 10 minutes or less), which requires high timeliness for data analysis. [0003] In terms of data statistical anal...
