Data management method and system for charging services

Abstract

The embodiment of the invention discloses a data management method and system for charging services. The method includes the steps that a shared physical memory expressed through a memory address is created and the memory address is directly mapped to virtual address space of multiple courses; basic data and calculating data, corresponding to the courses, in a memory database are loaded into the shared physical memory, wherein the calculating data are acquired by processing the basic data through a pricing application or a favorable application of the charging services.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data management method and system for billing services. Background technique [0002] The memory database is relative to the traditional disk relational database (such as Oracle, SQLServer). Traditional databases use disks to ensure persistent storage of data, while in-memory databases store data in memory, and all transactions / data access only involve memory. Therefore, compared with traditional relational databases, in-memory databases can achieve higher performance and better real-time performance. [0003] The billing business background includes applications such as collection, price approval, discount, daily rent, monthly rent, and credit control. The processes corresponding to these businesses often need to interact with the memory database during execution. The data delivered by them reaches G level, and the process Much of the data is stored in an in-memory database fo...

AI Technical Summary

Problems solved by technology

In an in-memory database, the data processed by each process is independent of each other, and each process uses a section of memory independently, which requires a large memory space

Moreover, when the processes perform their respective operations, they need to repeatedly access the memory database, which causes a large operational burden on the processor.

In addition, a large number of repeated access to the memory database reduces the data processing efficiency to a certain extent

Therefore, the in-memory database for single process is not suitable for the billing business, which has a large amount of data, many processes, and a data system with cumbersome operations.
