另外，尽管可以在保留现有关系数据库的同时使用NXD，但是这会在集成多个数据源的数据方面产生新的难题。
And, though they might use an NXD in addition to their relational database, this can create new challenges in the integration of data divided over multiple sources.
消息传递和数据库起了相互补充的作用，在许多情况下，同时使用消息传递和关系数据库可以产生比只使用它们中的一个好得多的解决方案。
Messaging and databases offer complementary strengths, and in many cases, using both messaging and relational databases together can yield a solution that is much better than either one by itself.
使用得当的防晒系数为8或更高的防晒霜在完全阻挡紫外线辐射的同时也阻止了维生素d的合成。
Used properly, sunscreens with an SPF of 8 or higher completely block UVB radiation and prevent synthesis of vitamin d.
LOAD实用程序的主要优点可同时用于XML数据和关系数据，例如数据不会被记录并自动使用并行功能提升性能。
The key advantages of the LOAD utility are the same for XML as for relational data, such as the data does not get logged and parallelism is automatically used to increase performance.
关系数据库的核心是以记录表示数据，记录存放在数据库表，数据库使用查询语言(SQL)对数据进行搜索与查询，同时，数据库对各个数据表进行关联。
The database offers a way to search the records using a query language, nowadays SQL. The database offers a way to correlate information from multiple tables.
同时还建议最好具有设计和实现基于. NET或J2EE的计算机应用程序以及使用关系数据库方面的经验。
Experience designing and implementing.net or J2EE-based computer applications, and working with relational databases is also recommended.
它还允许同时使用SQL和XML扩展(Xquery和Xpath)访问关系数据和XML数据。
It also allows for the use of SQL with XML extensions, Xquery and Xpath to access relational and XML data.
除了使用XQuery搜索XML数据和使用SQL搜索关系数据外，用户还可以在同一个查询中同时搜索关系数据和XML数据。
In addition to being able to use XQuery to search relational data and SQL to search XML data, users can issue a single query to search both relational data and XML data at the same time.
同时，在确定准则层对目标层的权重时使用了变异系数法。
At the same time, we use coefficient of differentiation method in determining the weights of criterion tier to target tier.
同时，使用了相关值-相关系数的理论对采样数据处理，通过检测极大值实现系统的测长。
Simultaneously, using the theory of the relevant -value and correlation coefficient to process the sample data, detecting the maximum value to realize measurement.
使用相互作用系数的方法分析桩—桩之间的相互作用，同时考虑桩的“加筋”对土的位移场的影响。
The interaction between piles was analyzed with interaction factors, and "restraint" action between piles was considered.
