ODS in incremental ETL process of CSP model

Parallel incremental ETL process is to improve the ODS data real-time effective way.Combine with communicating sequential processes theory of the incremental ETL process models,formal analysis of the incremental ETL process events in parallel execution environment,and the state of transformation process,this paper proposed the incremental ETL process proposed parallel scheduling algorithm to solve the incremental ETL process a parallel scheduling policy environment in question.Application and practice show that the model and algorithm with the source system load is small,and high real-time data.
