%X An optimization framework is provided in the paper ,and the logical optimization of ETL processes is researched.The optimization problem is modeled as a state-space search problem.Each ETL workflow is considered as a state and the state space is fabricated through a set of correct state transitions.Moreover , algorithms are provided towards the minimization of the execution cost of an ETL workflow .The theory and experiment result prove it to be efficient.
