Abstract: Simulated data generation for information system is an important way for providing data, which is needed in experiments, trials or exercises of information system. In this paper, the simulated data generation for information system was compared with other correlative fields, such as software test data generation, sample data expansion and virtual reality,and its research orientation was discussed. Research contents of the simulated data generation for information system were summarized. A typical system architecture framework for the simulated data generation for information system was proposed. The framework was divided into three layers. They are data layer,intermediate layer and generation layer. At last, the future research directions of the simulated data generation for information system were analyzed.
