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.

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.

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.

To meet the demand for the geotechnical information system management, this paper has put forward a plan to develop the management information system by using GIS and commercial database management technology. It has also described and analyzed the development of the function modules of the system and designed its module structure architecture for further development of the system. The GIS and database technology may be applied in managing, analyzing and evaluating the sea-volume geotechnical information data and help realize information sharing and provide policy-making support for the city planning, construction and management.

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.

A design thought based on ergonomics constraint is introduced to machine tool operating components design in this paper, and a design method of machine tool operating components is researched and provided which is realized by applying database technology and Secondary development technology based a '3D entity parameterized modeling software system platform. This method tests and verifies instrumentalizing the knowledge about industrial design and ergonomics.
