- Finally, two lossless join decomposition algorithms for transforming an XML document's DTD into XNF-1 and XNF-2 respectively are given.
最后给出了把一个XML文档的DTD无损联接地分解成符合XNF-1和XNF-2的两个算法。 - Implementing and Testing the Lossless Join Decomposition of Fuzzy Relations
模糊关系无损连接分解的实现及检验 - Two conceptions of fuzzy null value join dependency are given. One is concluded on the basis of lossless join, the other is concluded on the basis of fuzzy null value multi value dependency. The equivalence between two conceptions is demonstrated.
给出模糊空值连接依赖的两个概念，一个是基于无损连接得出的，另一个是类似模糊空值多值依赖给出的，并证明了两个概念的等价性。 - The decomposition of a database schema to meet preserving functional dependency, lossless join, BCNF and no-α ring is one of the important problems of the theoretical research of a database and its application.
一个数据库模式分解为满足保持函数依赖、无损联接性、BCNF且无α环是数据库理论和应用研究的重要问题之一。 - Lossless Join Decomposition and Minimum Decomposition of Relational Schema
关系模式的无损连接及最简分解 - The traditional algorithm for decomposing a relation scheme into BCNF with a lossless join must determine whether a relation scheme is in BCNF. Unfortunately, it has been proved that the determination is NP-complete.
传统的关系模式的BCNF分解算法必须判断一个关系模式是否为BCNF，该判断是一个NP-完全问题，因此传统算法缺乏实用性。 - The concept of lossless join decomposition for DTDs is also defined by the relational representation of DTDs.
