| Abstract: | A data allocation strategy based on electromagnetism-like mechanism algorithm was proposed in this paper in order to slove the problems that the cost formula is too complex,the efficiency is low and the result is much worse than the optimal allocation.The purpose is to find a highly efficient data allocation strategy of distributed database.The results show that the data allocation strategy proposed in this paper has a higher efficiency than traditional data allocation strategy and is much closer to the best result.This strategy can be applied to the construction of distributed database of Shaanxi lightning-protecting management information system. |
