The invention discloses a service platform integration method based on big data. The method comprises the following steps: (1) acquiring multi-source heterogeneous data; (2) integrating the acquired multi-source heterogeneous data, and storing the integrated data in an Hbase database; (3) using Hive to perform ETL treatment on the integrated data which is stored in the Hbase database, and storing in the Hbase database, cleaning the data which is stored in the Hbase database, to obtain clean data, and storing the clean data in the Hbase database; (4) based on an Hadoop technology, performing modeling analysis on the obtained clean data, and storing an analysis result in an Hive database; (5) using a service-oriented architecture based on SOA to establish a data exchange and shared service bus, and then based on the service bus, establishing a data exchange architecture, and through the data exchange architecture, pushing the analysis result which is stored in the Hive database to a business application system database. The method effectively reduces communication cost and time cost, and improves data effective utilization rate.
