In most cases, parsing XML documents to relational data can be done in a streaming fashion without requiring much memory and regardless of how big the document is. 在大多数情况下,XML文档到关系型数据的解析可通过串流方式完成,而无需太多内存且不管文档有多大。
If the relational record was modified more recently, save the Notes document without making any changes. 如果关系记录的修改时间更近,则保存文档而无需作任何更改。
This allows the metrics to be accessed repeatedly in relational format without having to parse the XML document on each access. 这使得指标可以以关系格式重复访问,而无需每次访问都解析XML文档。
In our sample table, values in the COMMENT column ( a relational column) can be used to isolate the type of trade recorded in the DOCUMENT column ( an XML column). 在我们的样例表中,COMMENT列(一个关系列)中的值可以用于分隔记录在DOCUMENT列(一个XML列)中的交易类型。
If you run LEI6.0 or later, you can use a Virtual Documents activity to create Notes lookup records that are stored entirely in the relational database. 如果运行的是LEI6.0或更新版本,您可以使用VirtualDocument活动来创建完全存储在关系数据库中的Notes查找记录。
The opposite operations can either be restricted or can be done using similar stored procedures ( update in the relational column updates the XML document too). 也可以使用类似的存储过程限制或执行相反的操作(更新关系列导致同时更新XML文档)。
Decomposed to existing relational tables using document access definition ( DAD) mapping. 使用文档访问定义(DAD)分解到现有的关系表。
The second table ( xmlrpdb. atom_site) contains one relational row for each atom coordinate ( i.e., for each element in a PDBML document). 第二个表(xmlrpdb.atomsite)包含了每个原子坐标的一个关系行(即,PDBML文档中的每个元素)。
Different from the update of relational tables, XML update needs to take the document order of nodes into account. 与关系表的更新不同,XML更新要考虑到节点的文档顺序。
Development Forecast of China Snowboarding from the Relational Documentary Information Research on Methods of Knowledge Organization and Content Revelation of Document Information 从单板滑雪文献研究探索项目发展措施文献信息知识组织与内容揭示方法探究
If we choose to implement persistence using a document store instead of a relational database, which collections of objects would represent a single document? 若是我们选择用文档存储庖代关系数据库来实现对峙,哪些对象凑集默示一个单一的文档?
The paper discusses, analyzes, compares two kind of XML data storage patterns based on relational database document pattern and element pattern. 本文论述、分析和比较了基于关系型数据库的XML数据的文档存储模式和元素存储模式。
In the database subsystem, the retrieved documents are represented by the fuzzy relational matrix of index-terms-documents, for each index term is weighted by a numerical weight according to its presence frequency in the document. 在数据库子系统,用索引词&文档模糊矩阵表示待检索的文档,对每个索引词,根据其在文档中的出现频率大小,引入了数值权重;
This software can extract data from a majority of structurized or semi-structurized data source, such as relational database, Excel file, formatted text file and XML document. 本软件支持对大部分结构化和半结构化数据的析取,包括各种关系数据库,Excel表格,有分隔符的文本文件,XML文件。
In the fifth Chapter, we set up a series of mapping algorithmic rules by analyzing the mapping principles from the Relational Database to the XML document. 第五章分析了关系数据库到XML文档的映射,制定了一系列映射规则并给出若干映射算法。
Based on the analysis of the fixed_lenght fields in relational database system, the paper introduce a usable storge and retrieval method to process the flexible_length document information and save the storge space. 本文从关系型数据库系统字段定长出发,通过分析提出了一种能灵活处理变长文献信息,节约外存空间的数据存取方法。
By analysis of the data conversion methods for converting relational database to XML document, it puts forward a new ASP-based method, which can be used to deal with large XML document. The method is put into practice in a factory. 在分析现有关系数据库转化为XML文档的方法的基础上,提出了一种基于ASP技术的XML数据转换方法,用以处理大型XML文件,并在企业ERP异地协同设计中得以验证。
Under the drive of requirement and technology, how to resolve the question of storing XML data by using an RDB and publishing relational data as an XML document is a hotspot. 在需求和技术的驱动下,如何解决基于关系数据库的XML存储和出版是近年来研究人员比较关注的一个课题。
But, it is noticed that most business data, even for new web-based applications, have and will be stored in relational databases. So it is necessary to publish relational data as an XML document. 然而,必须看到即使在全新的基于Web的应用中,大量的数据已经并将继续在关系数据库中存储和管理,这就有必要将关系数据出版为XML文档。
