Credit card core system open type bill calculation and query system based on big data

Abstract

The invention discloses a credit card core system open bill calculation and query system based on big data, and the system comprises: an authorization service which is used for the generation of authorization data; an account service which is used for generating bill-related original data according to authorization of the authorization service; a data and application service which comprises a billquery service, a data acquisition and transmission module and a bill calculation module, wherein the data and application service synchronizes original data to the HBASE cluster and the ES cluster inreal time through the data acquisition and transmission module, and the bill calculation module processes bill information in batches through Hive, generates bill data in a specified format for a bill corresponding system to use; and the peripheral system which acquires bill information by accessing the bill query service and synchronizes the data to the Hive cluster in an offline synchronizationmode. Data intercommunication can be achieved, and the effectiveness of query is improved.

Description

technical field [0001] The invention relates to the field of network information technology, in particular to an open bill calculation and query system of a credit card core system based on big data. Background technique [0002] With the advent of the information age and the vigorous development of online shopping and online transactions, people are using more and more electronic payment functions, and a large amount of bill information will be generated along with it. With the explosive growth of billing data, the original relational database query architecture can no longer meet the needs of a large amount of data query. When the amount of data grows to a certain level, the query and storage of data are facing huge challenges. When the data If the amount exceeds a certain level, it may affect the timeliness and performance of bill query, and it will also bring huge challenges to system maintenance. [0003] However, the existing bill inquiry service is out of touch with ...

With the explosive growth of billing data, the original relational database query architecture can no longer meet the needs of a large amount of data query. When the amount of data grows to a certain level, the query and storage of data are facing huge challenges. When the data After the amount exceeds a certain level, it may affect the timeliness and performance of bill query, and it will also bring huge challenges to system maintenance.

[0003] However, the existing bill query service is out of touch with bank customers, accounts, and card information, and cannot provide instant bill query services
