As XML has undoubtedly become a standard for data representation, it is inevitable to propose and implement techniques for efficient managing of XML data. A natural alternative is to exploit features and functions of (object-)relational database systems, i.e. to rely on their long theoretical and practical history. The main concern of such techniques is the(More)
Recently XML is quickly becoming a crucial format for representing and exchanging information. However this tendency brings an essential demand for effective storage and management of XML documents. As XML technology has many database features (e.g. storage strategy, query languages, schemes, programming interfaces, etc.), one possible solution can be found(More)
The unprecedented volume of information on the Web brings the practical difficulties for the information consumers to assess the quality of information. The wide variety of web users and distinct situations at their hands pose the difficulties to the quality assessment (QA) process, which must be customizable according to the information consumer’s needs.(More)
As XML has become a standard for data representation, it is inevitable to propose and implement techniques for efficient managing of XML data. A natural alternative is to exploit features and functions of (O)RDBMSs, i.e. to rely on their long theoretical and practical history. The main concern of such techniques is the choice of an appropriate(More)
As XML technologies have undoubtedly become a standard for data representation, it is inevitable to provide efficient implementations of W3C recommendations. A possible optimization of particular types of techniques can be found in exploitation of similarity of XML data and/or matching of XML patterns. In this paper we provide an overview and classification(More)
IntroductIon Without any doubt, the eXtensible Markup Language (XML) (Bray et al., 2006) is currently one of the most popular formats for data representation. Its wide popularity naturally invoked an enormous endeavour to propose faster and more efficient methods and tools for managing and processing of XML data. Soon it was possible to distinguish several(More)
XML is presently considered as one of the best standards for data representation. But with its growing usage the problem of effective processing of XML documents arises. A natural idea is to store and manage XML data in currently existing (O)RDBMS. At present there is a plenty of such techniques, each of which has its advantages and disadvantages, whereas(More)
The XML has undoubtedly become a standard for data representation and manipulation. But most of XML documents are still created without the respective description of their structure, i.e. an XML schema. Hence, in this paper we focus on the problem of automatic inferring of an XML schema for a given sample set of XML documents. We provide an overview and(More)
Web services as a basic instrument for inter-system communication are expanding rapidly. This causes an increased interest in effective integration into the respective complex systems. However, manual integration and management of evolution of the XML formats may be very hard. In this paper we study the possibilities of reverse engineering of XML schemas. A(More)
Most XSLT/XQuery tools provide editing and transformation support. Some provide also debugging and profiling support. However there is a lot more to do in order to have an XSLT/XQuery IDE similar with today’s Java IDEs for instance. oXygen started to walk on this road providing a number of advanced development features. An overview of the features that(More)
