xml-based applications widely apply to data exchange in EC and digital archives. However, the study of compressing native xml databases has been surprisingly neglected, especially for the huge amount of data and the rapidly updatable database. These two factors give rise to our interest, and motivate us to develop an approach to efficiently compress native xml databases and dynamically maintaining a set of compression rules when insertion, deletion, or modification functions in databases. This approach is to utilize data mining technology and association rules, to mine all frequent patterns. We proposed a frequent tag and character data pattern split tree (FTCP-split tree) to fast generate the set of association patterns. Then we convert these frequent patterns into compression rules, which would be used to compress native xml databases. The question which we must consider next is how to dynamically maintain xml database compression when xml documents are inserted, deleted, or modified. We propose a compression approach with dynamic maintenance on native xml databases to deal with it. The results of preliminary experiment indicate that the compression rate of our research is higher than the common compression software as ZIP and RAR.

Due the popularity of xml, an increasingly large amount of business transactions encoded in xml have been exchanged on-line. Currently there are two approaches to process and manage these xml data. One is to store them in relational databases, and the other is to store them in recently-developed native xml databases. There is no conclusion yet as to which approach suits better for contemporary business information systems. Also, the effectiveness of native xml databases used in daily operational systems has not been completely investigated. Therefore, in this paper, we provide: (1) a complete and systematic survey of the current development and challenges of processing xml data in relational and native xml databases, (2) a useful benchmark for IT practitioners who need to process xml data effectively, (3) experimental results and detailed analysis which reveal several interesting tips that can be helpful to xml document designers, and (4) a conclusion, based on the findings of using native xml databases in EDI processes, that it is practical to use native xml databases for daily operations although our experimental results showed that relational database systems outperform native xml databases in processing xml data.

In IEC61850 substation automation systems (SASs), substation configuration description language (SCL) is suggested to assure seamless information exchange among various intelligent electronic devices (IEDs) from different manufacturers in the form of unambiguous and standardized xml. In the paper, native xml database (NXD) is proposed to store and manage SCL files since NXD takes advantage over xml enabled database (XED) in maintaining information integrity that is the most important factor of SCL file management. And the detailed process of SCL file dynamic implementation in IEDs is demonstrated. According to information with different communication real-time requirements, configuration information from SCL files will be extracted in advance or only when the information is used. Finally, a testbed built by open source software Libxml2 under Linux system verifies the effectiveness of SCL file information extraction using Xpath.

In this paper we describe DeVisa, a Web system for scoring and management of data mining models. The system has been designed to provide unified access to different prediction models using standard technologies based on xml. The prediction models are serialized in PMML format and managed using a native xml database system. The system provides functions such as scoring, model comparison, model selection or sequencing through a web service interface. DeVisa also defines a specialized PMML query language named PMQL used for specifying client requests and interaction with PMML repository. The paper analyzes the system's architecture and functionality and discusses its use as a tool for researchers.

With rapid increase of semistructured data over the Web, xml becomes popular to represent such data and emerges as a de facto standard for information exchange among e-business applications. Since xml data are widely distributed, new native xml database systems, which are specifically tailored for managing such data, become necessary. Unlike data in conventional databases, xml has special characteristics and constraints, thus, well-defined architectural framework for conventional databases are not completely relevant to be adopted in native databases. Current state-of-the-art native databases employed their own architectures in their database designs, as a result, they are inconsistent and there is still lack of a common architectural framework that can be referenced by future xml database designers. We aim to fulfill this requirement. In this paper we propose a general and an extended architectural frameworks that are derived from our practical experience on designing an efficient storage for xml data while preserving desirable features and possible constraints. The validation demonstrates that the proposed framework covers the architectures employed in current state-of-the-art native database systems.

This paper presents a system that is designed to make possible the organization and search within the collected digitized material of intangible cultural heritage. The motivation for building the system was a vast quantity of multimedia documents collected by a team from the Institute for Balkan Studies in Belgrade. The main topic of their research were linguistic properties of speeches that are used in various places in the Balkans by different groups of people. This paper deals with a prototype system that enables the annotation of the collected material and its organization into a native xml database through a graphical interface. The system enables the search of the database and the presentation of digitized multimedia documents and spatial as well as non-spatial information of the queried data. The multimedia content can be read, listened to or watched while spatial properties are presented on the graphics that consists of geographic regions in the Balkans. The system also enables spatial queries by consulting the graph of geographic regions.

Effective storage of EMR data is the foundation of the rapid development of EMR. This paper analyses and compares the three traditional storage pattern of EMR data firstly, and then proposes a combination storage plan using ralational databse and native xml database with fine-grained structure granularity of EMR data and according to the HL7 CDA, which is the international de facto standard of EMR. We refined and evaluated this solution by experiments, and it is proved that this storage plan not only could reduce the EMR data storage space and the query time complexity effectively, but also could facilitate the clinicians and researcher to use EMR data for statistical medical information, clinical diagnosis and other areas in the later period.

This paper proposes an approach and demonstrates its application for cross- border exchange of clinical documents oriented towards the use of archetype concepts and international patient summary standards adopted in the European Union. A novelty in this approach is the management of native xml instances of an archetype concept in the CEN 13606 standard by means of a native xml database and xml technologies. The computer experiments demonstrate that it is suitable for representing relatively small clinical datasets such as those describing rare diseases like the Acromegaly illness, where the semantic context in the relatively small number of symptoms is practicable to tag in terms of SNOMED-CT terminology codes. Additionally, we demonstrate that the semantically enriched information model can facilitate secondary use of clinical data by visualizing the execution of queries based on standard terminologies. Finally, the compatibility of the information model with the IPS standard enables sharing of clinical data among different information models.

Accounting system meters resource usage of jobs executed on the computing nodes, and provides interfaces to extract usage information for later auditing or charge bill generation in computational grid. Current accounting systems only support fer specialized grid middleware and provide deferred resource usage accounting. This paper presents a flexible resource accounting framework and service for GOS. A line-based log parsing framework is designed to reduce the accounting latency from dozens of hours to one minute. Moreover, this paper proposes an algorithm named SSQT to speed up storage of large amount of resource usage data, since the native xml database have performance defects. This framework has been implemented and deployed on CNGrid (China National Grid), which is now accounting for 10 sites in China.
