摘要

考虑一个表示移动对象及其位置信息的数据库。例如，对于表示出租车位置的数据库，典型的查询可能是:检索目前在33 N. Michigan Ave.， Chicago 1英里范围内的免费出租车(以接客户)。在军事中，移动对象数据库应用出现在数字战场的背景下，在民用工业中，它们出现在运输系统中。目前，移动对象数据库应用程序正在以一种特别的方式开发。数据库管理系统(DBMS)技术为开发这些应用程序提供了潜在的基础，但是目前还没有将DBMS用于此目的。原因是移动对象数据库应用程序需要一组关键的功能，而这些功能是现有dbms所缺乏的。我们的移动对象数据库(DOMINO)项目的目标是在现有dbms之上构建一个包含这些功能的信封。我们描述了问题和我们提出的解决方案。

Moving objects databases: issues and solutions

Consider a database that represents information about moving objects and their location. For example, for a database representing the location of taxi-cabs a typical query may be: retrieve the free cabs that are currently within 1 mile of 33 N. Michigan Ave., Chicago (to pickup a customer). In the military, moving object database applications arise in the context of the digital battlefield and in the civilian industry they arise in transportation systems. Currently, moving object database applications are being developed in an ad hoc fashion. Database management system (DBMS) technology provides a potential foundation upon which to develop these applications, however DBMSs are currently not used for this purpose. The reason is that there is a critical set of capabilities that are needed by moving object database applications and are lacking in existing DBMSs. The objective of our Databases fOr MovINg Objects (DOMINO) project is to build an envelope containing these capabilities on top of existing DBMSs. We describe the problems and our proposed solutions.
