Bitemporal data can also be used in history tables. 双时间数据也可以用于历史表中。
Bitemporal tables allow you to manage data with both system and business time simultaneously, combining the benefits of both concepts. 双时间表支持同时使用系统时间和业务时间来管理数据,结合了这两个概念的好处。
Bitemporal framework from ErvaCon is an open source project created based on the Temporal Patterns to address the time related data requirements in rich domain models. 来自ErvaCon的Bitemporal框架是一个开源项目,它基于时态模式(TemporalPatterns)而创建,用来解决富领域模型中的时间相关数据的需求。
Research on Bitemporal Ontology and Application in Information Integration System 双时态本体模型及其在信息集成系统中的应用研究
Bitemporal 2D-spatial index& BT2D-Index was proposed based on 2R-Tree. 提出了一种基于2R树的双时态二维空间索引模型BT2DIndex。
This paper proposed a spatiotemporal data model for supporting 3D spatial and bitemporal domain. 建立了一种支持三维空间和双时态的时空模型,给出了模型的形式化定义,讨论了时空数据类型。
An Efficient Bitemporal Index Technology 一种有效的双时态索引技术
Results: Chinese true word test showed significant activation in left frontal lobe, precentral gyrus ( BA6), occipital lobe ( BA18), and slight activation in left parietal lobe, postcentral gyrus ( BA3), right inferior frontal gyrus ( BA9) and bitemporal lobe; 结果:汉字真字刺激在左额叶、中央前回(BA6)及枕叶(BA18)显著激活;左顶叶、中央后回(BA3)、右额下回(BA9)及双侧颞叶少量激活。
Type C closely resembles nonfunctioning pituitary adenomas with bitemporal hemianopsia and hypopituitarism. C型类似无功能垂体腺瘤,除视野缺损外,还有双颞侧偏盲。
The paper briefly introduce the production, development and the application prospect of TGIS, elaborates the concept of temporal database and educe the bitemporal theory. 本文简要介绍了时态GIS的产生、发展及应用前景,阐述了时态数据库的概念,引入了双时态理论。
A bitemporal spatiotemporal data model and index 一种双时态时空模型和索引机制
According to the requirements of development of spatial database, this paper introduces bitemporal theory which belongs to the field of temporal information management, then applies the theory to produce a spatio-temporal conceptual data model which can manage temporal transaction information. 根据空间数据库的发展需要,该文将时态信息管理领域中的双时态理论引入到其中,形成了一个可处理时间事务信息的时空数据概念模型。
An Efficient Bitemporal Index Model Based on the Temporal Middleware 一种基于时态中间件的高效双时态索引模型
The temporal middleware does not support the index of bitemporal data, which include the transaction time and valid time. By using the proper data transformation and query transformation, the bitemporal data can be trans-ferred to the data of 4R index. 当前的时态数据库中间件不支持包含事务时间和有效时间的双时态数据索引,通过使用适当的数据变换和查询变换,可将双时态数据转化为R树可索引的数据。
Bitemporal database which can reflect not only the historical information of the incidents treated with but also the temporal information of meta events in the system has attracted increasing attention. 时态数据库中既反映能被处理事件的历史性信息又能体现系统中元事件的时态信息的双时态数据库日益受到人们的关注。
Like spatial data, bitemporal data has associated two-dimensional data regions. 与空间数据一样,双时态数据也构成了一个二维数据区域。
