Real-time calculation query system and method based on B2B mall

The invention relates to a real-time calculation query system and a method based on a B2B mall. The system comprises a business database, an HDFS distributed storage system, a Kudu column database, afront-end WEB system, a real-time collection and forwarding unit, a Shell script and Hive. Business data are collected into the Kudu column type database in real time through the big data platform, the timeliness of the data is guaranteed, a calculation request of a user is input and submitted in real time through the front-end WEB system, and a calculation result is obtained in time through the operational capability of the big data platform and used for supporting decision making. 本发明涉及一种基于B2B商城的实时计算查询系统及方法，该系统包括：业务数据库、HDFS分布式存储系统、Kudu列式数据库、前端WEB系统、实时采集转发单元、Shell脚本以及Hive。本发明业务数据通过大数据平台实时收集入Kudu列式数据库，保证了数据的及时性，用户的计算请求通过前端WEB系统实时录入提交，并通过大数据平台的运算能力，及时得到计算结果，用来支撑决策。
