摘要 通过对目前已有的时空数据库技术在易于实现的时空查询代数方面进行的深入研究,提出了一种基于对象关系的时空查询代数stor-algebra,从数据结构和代数操作两方面进行了详细描述.stor-algebra兼容关系代数,并可在对象关系数据库管理系统上实现,可作为时空查询处理系统的代数基础. Stor-algebra, spatiotemporal query algebra, was presented based on object-relational model, and then was described in detail from its data structures to algebra operations. It has the nature and characteristics of relational algebra and can be implemented based on object-relational database management system. It is the algebra foundation of spatiotemporal query optimization.
