Abstract

Through real-time monitoring police system log,the detail data of operational data store ODS are real-time elicited from system log to ODS,meanwhile this mechanism synchronizes the ODS data and business system database in second grade.Real-time ODS based mechanism establishes a Log-ODS-DW three-level model Police DW system,real-time OLAP based query,the cubes of ODS and DW fresh data dynamically,serving real-time OLAP service.The authors put forward a dynamic DW infrastructure which can offer real-time police decision analysis with the features of little burthen on business system,real time,rapid query and meet a need of police system.
