When i first heard of native xml database systems about two years ago, i completely ignored them thinking that it was just hype 大约两年前当我第一次听说native-xml数据库系统时,我完全没当一回事,并且认为它只是一种宣传而已。
native xml database is just the one to provide the really efficient storage and retrieval ability for those unstructured information described by xml 利用nativexml数据库可以为采用xml所表示的非结构化信息提供真正有效的存储和信息获取能力。
native xml database defines a logical model for xml document, with which to store the document as a basic logical unit, and is independent to the bottom physical storage model nativexml数据库为xml文档定义了一个(逻辑)模型进行存取操作,具有与底层的物理存储模型无关的特性。
In this article, frank cohen describes a new strategy and techniques for accelerating soa performance through the use of xml, xquery, and native xml database technology in the soa mid-tier 在本文中,frankcohen将介绍如何通过在soa中间层使用xml、xquery和本机xml数据库技术来提高soa性能的战略和技术。
The combination of xquery and a native xml database delivers a service that plays-back the previously cached response data, provided the request matches the previous request and the data is still fresh xquery和本机xml数据库提供了重用以前缓冲响应数据的服务,只要请求与以前的请求匹配并且数据仍然不过时。
Lastly, fastsoa uses a native xml database for mid-tier caching because soa data is normally encoded in xml format, and relational databases do a poor job of persisting and indexing hierarchical unstructured data such as xml 最后,fastsoa使用本机xml数据库作为中间层缓冲,因为soa数据通常采用xml编码格式,而关系数据库在持久存储和索引xml这样的层次性非结构化数据方面有很大不足。
After analyzing the benefits and drawbacks of both the two kinds of xml databases in managing xml data, this thesis explored the technology and method of managing gml data using native xml database, including the storing, querying and modifying of gml documents 本文分析了两种数据库对xml数据管理的优缺点后,探讨了采用nativexml数据库对gml文档进行管理的技术和方法,包括gml文档的存储、查询以及更新等。
Firstly, in this paper, we review the histories of xml and xml database, and all kinds of data models used widely now . then we review traditional access control policies and policies specially used on xml, and present a new expression method of access set on xml based on child tree of w3c data model . and we bring rbac model into xml database and present a new xml access model x-rbac . because the usage of data in databases has high frequency, we present an ids model based on access set density to logging the potential security threats . and then we introduce the design and implementation of a prototype of our native xml database nhx and its access control system . finally, we draw a conclusion for this paper and the future work 本文首先回顾了xml及xml数据库的历史,并总结了目前广泛使用的xml数据模型,在分析了各种传统数据库访问控制策略,以及xml的专有访问控制策略的优缺点后,基于w3c的xml数据模型,提出了一种基于子树的具有高弹性的便于实现的的访问区域表示法,并将rbac模型引入进来,提出了一种适用于xml数据库的访问控制模型x-rbac,同时为了区分xml数据库访问中的合法访问和合理访问,我们根据数据库访问具有频繁性这一特征,提出了一种基于区域访问密度的入侵检测模型(ids),以对隐藏在正常访问中的潜在安全威胁进行报警和日志。
With rapid development of information science, xml is more and more widely used in every field of the world . and xml database is brought to manage this semi-structural files . according to the definition of xml : db, there are three kinds of xml databases, which are native xml database, xml enabled database and mixed xml database . because the application environment of the xml database is so complicated as legacy rdbms, it faces serious security problems . this paper is mainly on native xml database and its access control 随着信息技术的迅速发展,xml正在各个领域被越来越广泛的应用,为了有效的管理这种半结构化的数据,xml数据库的概念被提出。根据xml:db的定义,xml数据库可以分为xml本源数据库、支持xml的数据库、xml混合数据库。由于xml数据库和传统的关系型数据一样被广泛的应用在复杂的网络环境中,因此它面临着同样严重的安全问题。
