Native Xml Database

IETM database standardized on S1000D consists of XML documents. In view of former relational database treat XML documents defectively, design storage and index pattern of IETM database which is based on features of module and information object standardized on S1000D with relational XML database technology. There is a certain significance to broaden.

Query Optimizers

Since the very beginning of query processing in database systems, cost-based query optimization has been the essential strategy for effectively answering complex queries on large documents. XML documents can be efficiently stored and processed using native XML database management systems. Even though such systems can choose from a huge repertoire of join operators (e. g., Structural Joins and Holistic Twig Joins) and various index access operators to efficiently evaluate queries on XML documents, the development of full-fledged XML query optimizers is still in its infancy. Especially the evaluation of complex XQuery expressions using these operators is not well understood and needs further research. The extensible, rule-based, and cost-based XML query optimization framework proposed in this chapter, serves as a testbed for exploring how and whether well-known concepts from relational query optimization (e. g., join reordering) can be reused and which new techniques can make a significant contribution to speed-up query execution. Using the best practices and an appropriate cost model that will be developed using this framework, it can be turned into a robust cost-based XML query optimizer in the future.

The Web

The Web and XML have influenced all walks of lives of those who transact business over the Internet. People like to do their transactions from their homes to save time and money. For example, customers like to pay their utility bills and other banking transactions from their homes through the Internet. Most companies, including banks, maintain their records using relational database technology. But the traditional relational database technology is unable to provide all these new facilities to the customers. To make the traditional relational database technology cope with the Web and XML technologies, we need a transformation between the XML technology and the relational database technology as middleware. In this chapter, we present a new and simpler algorithm for this purpose. This algorithm transforms a schema of a XML document into a relational database schema, taking into consideration the requirement of relational database technology.

Database is the foundation of making IETM, database structure has great influence to the TETM production method and use efficiency. Aiming at the defects when using relational database to process XML documents, According to the characteristics of IETM data module and information objects under S1000D standard, native XML database needed to meeting the conditions were analyzed, using a native XML database technology to structure IETM data Module and information set; and giving data module code, information objects, information control composition structure codes of the data module structure, gives the design method of IETM database storage and index model, which can effectively avoid the traditional the deficiency of IETM database support for XML technology.

Mapping Scheme

<p>With XML as the leading standard for data representation over the Web, it is crucial to store and query XML data. However, relational databases are the dominant database technology in most organizations. Thus, replacing relational database with a pure XML database is not a wise choice. One most prominent solution is to map XML into relational database. This paper introduces a robust labeling scheme which is a hybrid labeling scheme combining the beauty features of extended range and ORDPATH schemes to supports dynamic updates. In addition, we also proposed a mapping scheme based on the hybrid labeling scheme. Our proposed approach is evaluated in terms of (i) loading time, (ii) storage size, (iii) query retrieval time, and (iv) dynamic updates time, as compared to ORDPATH and ME schemes. The experimental evaluation results shows that our proposed approach is scalable to support huge datasets and dynamic updates.</p>

Exchange Data

Ever since the Extensible Markup Language (XML) (W3C, 1998b) began to be used to exchange data between diverse sources, interest has grown in deploying data management technology to store and query XML documents. A number of approaches propose to adapt relational database technology to store and maintain XML documents (Deutsch, Fernandez & Suciu, 1999; Florescu & Kossmann, 1999; Klettke & Meyer, 2000; Shanmugasundaram et al., 1999; Tatarinov et al., 2002; O’Neil et al., 2004). The advantage is that the XML repository inherits all the power of mature relational technology like indexes and transaction management. For XML-enabled querying, a declarative query language (Chamberlin et al., 2001) is available.

Coordination Tool

This paper explores the design and development considerations inherent in the production and deployment of a web-based programme management coordination tool (PMCT) that has been built on a native XML database (NXD). In selecting a small to medium sized enterprise (SME) as a target, specific problems had to be addressed. These practical issues are highlighted along with assessments and analysis of the suitability of the NXD chosen for the function. The paper offers suggestions relating to the cause and effect of underlying trends currently affecting SME’s within the telecommunications sector, and it shows how the management tools and the technologies that they might employ to derive benefit, need careful alignment with the purpose to be effective.
