摘要 已有的时空数据库研究集中在模型和语言上,缺乏时空数据库的系统实现。针对这一问题,给出了一种应用Informix数据刀片技术进行时空数据库系统实现的方法,论述了底层的时空数据模型、时空数据刀片的实现过程以及实验结果。 The previous researches on spatiotemporal databases were concentrated on data models and languages, they are not the implementation of spatiotemporal database systems. Based on this problem, a method of implementing spatiotemporal database systems using the Informix datablade technology is presented. The detailed fundamental spatiotemporal data model and the procedure of implementing spatiotemporal datablade are discussed, as well as the experimental results.
