| 摘 要： | 随着XML规范的制定和推广，XML数据管理技术受到数据库界广泛重视，XML数据的存储是XML数据管理的关键．研究了利用数据库技术和人工智能技术，为XML数据的关系存储提供一种灵活的策略．首次提出了代价驱动的基于遗传算法的关系存储策略CDGABRS，针对不同的用户和查询模型，产生不同的映射模型方案，引进遗传算法，计算对应的系统开销，从中求出使系统的存储代价和查询代价最优的关系存储方案．实验证明了CDGABRS方法的可行性和高效性．

| Abstract: | With the development of XML, XML data management technology is receiving more and more attention, and XML storage is key in the XML data management system Here, a new method is presented, which is based on the cost model for XML data in a relational database in order to provide different data schema for different users and requirements Then, this XML storage problem is turned into an optimal problem, and a genetic algorithm is introduced to solve this problem Experiments are done to test this method and it is shown that this method is feasible and efficient, and it can be used to design different schema according to different user query requirements |
