| 2. | To add a global query to a dataset
向数据集添加全局查询 |
| 3. | Global queries are sql queries that return either a single scalar value or no value
“全局查询”是返回单个（标量）值或不返回任何值的sql查询。 |
| 4. | You add global queries by running the tableadapter query configuration wizard from within the
可以通过从“数据集设计器”运行“ tableadapter查询配置向导”添加全局查询。 |
| 5. | Therefore , through the self - defined globe - sql , broker manipulate sql so as to control every table in database
再通过自定义的全局查询语言，代理完成sql操作，以达到操作数据库中各表的目的。 |
| 6. | Dragging a query onto a table adds the query to that table , whereas dragging a query onto an empty area of the
将查询拖动到表上可将该查询添加到该表，而将查询拖动到“数据集设计器”的空白区域上会创建全局查询。 |
| 7. | The ability to aggregate arbitrary numbers of such wsdl rdf descriptions into a database , and do global queries is one immediate benefit of this rdf mapping for developers
对于开发者来说，这一rdf映射的直接好处在于能够把任意数目的这类wsdl / rdf描述聚集到数据库并进行全局查询。 |
| 8. | This paper improves on the existent methods of schema integration by analysis and comparing them and combining xml with them . moreover , the global schema and mapping rules according to xml standard are generated
本文在分析比较已有模式集成方法的基础上，结合xml作为数据模型描述语言的优势，将xml技术应用于模式集成，改进了已有模式集成方法，生成符合xml标准的全局模式和模式映射规则，为全局查询处理奠定了基础。 |
| 9. | Second , the dissertation addresses the global query rewriting issues of the service oriented spatial data integration . query rewriting and optimization methods are presented based on equivalent transformation of relational operators . we study the data replication issues of spatial data services and presents strategies to deal with data fragmentation and service selection
其次,论文研究了面向空间数据服务集成的全局查询重构问题,在关系代数等价变换基础上提出了空间数据服务全局查询重构和优化方法,并提出了面向分布式空间区域查询的副本处理方法和资源选择策略。 |
| 10. | The paper also puts forth concrete solving methods about the following key problems in the realization of system : ( 1 ) middle operation logic layer is separated from the system . designing the three - architecture for the integrated system . ( 2 ) designing the uniform general data - describing mode
提出的主要解决方案有： ( 1 )从系统中分离出中间业务逻辑层，形成三层体系结构； ( 2 )设计了统一的公共数据描述模式； ( 3 )设计了基于sql的全局查询语言； ( 4 )实现了集成系统的动态生成。 |
