2) semantic constraint
语义约束
1.
Original semantic constraints in the conversion from XML DTD to relational mode;
XML DTD转换为关系模式的原语义约束
2.
Then the algorithm XTR is presented, and the method to preserve semantic constraints is discussed.
本文研究了XML模式,分析了已有的XML模式到关系模式的转换算法及其存在的问题,提出了新的转换算法XTR,并探讨了保留语义约束的方法。
3.
It describes how to transform relational schemas to XML schemas based on semantic constraints.
本文首先研究了关系模式的特点,然后针对XML的树型结构特点,研究了基于语义约束的从关系模式到XML模式的转换,最后给出了从关系模式到XML模式转换的算法RTS。
3) semantic stipulation
语义约定
1.
Based on the judgment that semantic stipulations have semi-sequential relationship, this paper divides IEC 61850 s semantic stipulation into two levels: SCADA semantic and substation semantic stipulation, also divides the application of IEC 61850 into generalized and specialized application accordingly.
依据语义约定具有偏序关系的论断,将IEC 61850的语义约定分为SCADA语义约定和变电站语义约定两个层次,相应地将对IEC 61850的应用分为广义应用和狭义应用。
4) semantic constraints
语义约束
1.
XML semantic constraints have been widely researched already,whereas most of them ignore a basic problem:the derivation of XML semantic constraints,which is the right topic of this paper.
文章讨论了XML语义约束的产生问题。
2.
In general, we made a deep and effective research on the hypermedia semantic constraints from application area independent to specific application area de.
提出了一种基于数据库模式的超媒体语义网络模型 ,该模型通过引入模式约束图 ,对超媒体系统中的关系约束进行了分类 ,并给出了相应的约束检测算法 ;通过引入视图机制提出了结构约束的概念 ;通过扩充模式约束图的属性 ,描述了超媒体特定应用领域的计算约束 ,从而从整体上对与应用领域无关至特定应用领域的语义约束进行了深入的研究 。
3.
The semantic constraints of data can be well preserved to ensure the non-loss of the conversion from XML schema to relation schema.
数据语义约束的完整保留是实现XML Schema向关系模式"无损"转换的关键问题。
5) semantic constrains
语义约束
1.
But the types of semantic constrains of ERL are not enough.
针对ERL描述的语义种类不齐全的问题,在ERL已能处理的语义约束之外,又给出了聚集语义、覆盖语义的描述和可满足性的判定方
