摘要： 数据服务作为一种面向跨域异构数据源的统一数据模型,能够将数据资源以服务的形式进行发布,并根据用户的数据需求,通过组合若干个数据服务生成数据组合视图。然而,由于数据源是自治的,当数据发生变化时,如何以最小的代价实时更新数据组合视图是数据服务技术需要解决的关键问题。为此,提出一种基于增量日志的数据组合视图定位更新方法,先根据数据源日志的增量变化获取最新变更数据,然后通过定位属性计算组合视图中差异元组的索引号,并根据变更类型直接对组合视图中的差异元组执行数据更新操作,最终给出了基于日志的更新数据实时获取算法和数据组合视图定位更新算法。在跨域异构电梯数据服务系统中对本更新方法进行了评价,结果表明,当变更元组数量所占比例远小于元组总数或数据组合视图的属性个数较多时,定位更新方法的更新效率比现有方法高。
