时空数据库查询处理系统的设计与实现 摘要 Researches on spatial and temporal databases have been done independentl时间和空间数据库进行了独立。 In terms of spatial databases, whenever a new object instance is inserted into a database, the old one should be deleted.空间数据库，每当一个新的对象实例插入到数据库中，旧的应删除。 It stands for the difficulty to manage efficiently the historical information about spatial object that has been changed with temporal evolution.它所代表的困难有效的历史信息空间管理对象已经改变时空演化。 In view of temporal databases, because it did not consider supporting spatial type and operation, it is extremely hard to manage directly spatial objects without any modification.鉴于时间数据库，因为它没有考虑支持的类型和运作空间，直接管理的空间物体极其难以作任何修改。 Nevertheless, because these research domains are closely related, an integration field, ie, spatiotemporal databases, has been launched.然而，由于这些研究领域是密切相关的，一个集成领域已经开始，即时空数据库。 Spatiotemporal databases support historical information as well as spatial management for the object at the same time and can deal with geometries changing over time.时空数据库支持的历史资料以及空间管理对象在同时可以处理几何形状变化。 They can be used in the various application areas such as geographic information system (GIS), urban plan system (UPS), and car navigation system (CNS), and so on.In this paper, we design not only the spatiotemporal query processing (STQP) system, but also implement them.它们可用于各种应用领域，如地理信息系统（ GIS ） ，城市规划系统公司（ UPS ） ，以及汽车导航系统（ CNS ） 本文中，我们的设计不仅是时空查询处理（ STQP ）系统，而且。 They include a spatiotemporal data model (STDM) that supports bitemporal concept for spatial objects.它们包括时空数据模型（） ，支持双时态概念的空间物体。 We also explain a specification of the spatiotemporal database query language, entitled as STQL as well.我们时空数据库查询语言，题为STQL。 Compared with the results of the previous researches, we insist that it is the first pilot system in the spatiotemporal database area that supports temporal concept and spatial expression as well.以前研究，我们坚在时空数据库领域它是第一个试点系统，支持时间和空间概念的表达。 作者关键词：时空数据库查询语言查询处理系统评价地理信息系统大部分的应用，如财务，营销，财产和资源的管理有共同的特征主要内容空间和时间变化的数据的语义。广泛的应用管理的空间，随时间或时空数（波伦年） 。 空间数据库的研究已
