The flexible and semi-structured eXtensible Markup Language (xml) is used in various application domains as well as the database field. The proposed xml harmonization system attempts to re-utilize existing markup languages by extracting and integrating them. This idea is analogous to the join operation in the database domain. When new structures are created, new document types are defined. Structures of xml instances can be viewed from various viewpoints, e.g. the relational database or the object-oriented database. In this work, we propose a new way to achieve harmonization, i.e., by defining axioms on atomic elements of the selected data structure. The advantage of using axioms is that it can be extended to other data structures easily. Measurements of harmonization are discussed, and harmonization examples are given to illustrate the axiom-based design principle.

This thesis aims to find a graph structure for representing xml documents and to implement the former representation for storing such documents. The graph structure, in fact, is the complete representation for the xml documents; this is dued to the id/idref attribute which could be present inside the xml document *** different graph structures have been defined on this thesis, they are called most granular and customizable representations. The first one is the simplest way for representing xml documents, while the second one makes some improvements for optimizing inserting, deleting, and querying *** implementation of the former graph structures is made over a new kind of database built specifically for storing semi-structured data, such database is called Neo. Neo database works only with three primitives: node, relationship, and property. Such data model represents a new solution compared to the traditional relational *** xml information manager implements two different API which work with the two former graph structure respectively. The first API works with the customizable representation, while the second one works with the customizable *** evaluations have been done over the second implemented API, and they showed that the implemented code is free of bugs and moreover that the customizable representation brings about some improvements on making queries over the stored data

Background: Geopolitical and economic crises force a growing number of people to leave their countries and search better employment opportunities abroad. Meanwhile, the highly competitive labor market provides opportunities for employees to change workplaces and job positions. Health assessment data collected during the occupational history is an essential resource for developing efficient occupational disease prevention strategies as well as for ensuring the physical and psychological well-being of newly appointed workers. The diversity in data representation is source for interoperability problems that are insufficiently explored in the existing literature. Objectives: This research aims to design a worker's occupational health assessment summary (OHAS) dataset that satisfies the requirements of an international standard for semantic interoperability in the use case for exchanging extracts of such data. The focus is on the need for a common OHAS standard at EU level allowing seamless exchange of OHAS at both cross-border and at the worker's country of origin level. Results: This paper proposes a novelty systematic approach ensuring semantic interoperability in the exchange of OHAS. Two use cases are explored in terms of UML sequence diagram. The OHAS dataset reflects common data requirements established in the national legislation of EU countries. Finally, an EN 13606 archetype of OHAS is designed by satisfying the requirements for semantic interoperability in the exchange of clinical data. Semantic interoperability of OHAS is demonstrated with realistic use case data. Conclusions: The designed static, non-volatile and reusable information model of OHAS developed in this paper allows to create EN 13606 archetype instances that are valid with respect to the Reference model and the datatypes of this standard. Thus, basic activities in the OHAS use case can be implemented in software, for example, by means of a native xml database as well as integrated into existing

Software-as-a-Service (SaaS) is now a hot issue in both academia and business. Multi-tenant data storage as a fundamental component of a SaaS system draws much attention. The need of scalability and multi-tenant support in SaaS makes traditional RDBMS unappealing and calls for a better data storage solution. In this paper, we categorize some proposed solutions and evaluate the performance of a native xml database (NXD) solution implemented on Berkeley DB xml. Experimental results show that the opportunity of applying NXD in SaaS has not yet arrived.
