Automatic Generation of XML DTDs from Conceptual Database Schemas

by unknown authors
"... Abstract: The goal of this article is to present an algorithm to simplify the automatic generation of descriptions of XML document structures. In particular we show how to obtain a DTD (document type definition) for data whose structure is described by a conceptual data model. An important objective ..."
Abstract - Add to MetaCart
objective of this translation is to preserve as much structural information from the conceptual schema as possible. This enables partial constraint checking by validating XML parsers and thus simplifies exchange of data between different databases, in particular the import of data in an XML document

Transforming Sem-ODM Semantic Schemas to DTDs

by Li Yang, Naphtali Rishe - Proceedings of the 43rd ACM Southeast Conference, ACMSE 2005. Kennesaw, GA , 2005
"... Exporting data in traditional databases as XML documents so that non-XML data can be accessed and exchanged seamlessly among applications has been studied in a number of projects. In this paper, we present an algorithm that automatically derives a Document Type Definition (DTD) from a Semantic Schem ..."

Deriving Conceptual Schema from XML Databases

by Oviliani Yenty Yuliana, Suphamit Chittayasothorn
"... In this paper, two concepts from different research areas are addressed together, namely functional dependency (FD) and multidimensional association rule (MAR). FD is a class of integrity constraints that have gained fundamental importance in relational database design. MAR is a class of patterns wh ..."

which has been studied rigorously in data mining. We employ MAR to mine the interesting rules from XML Databases. The mined interesting rules are considered as candidate FDs whose all confidence itemsets are 100%. To prune the weak rules, we pay attention to support and correlation itemsets. The final

Inferring XML Schema Definitions from XML Data

by Geert Jan Bex, Frank Neven, et al. , 2007
"... Although the presence of a schema enables many optimizations for operations on XML documents, recent studies have shown that many XML documents in practice either do not refer to a schema, or refer to a syntactically incorrect one. It is therefore of utmost importance to provide tools and techniques ..."

and techniques that can automatically generate schemas from sets of sample documents. While previous work in this area has mostly focused on the inference of Document Type Definitions (DTDs for short), we will consider the inference of XML Schema Definitions (XSDs for short) – the increasingly popular schema

Conceptual Modeling for Customized XML Schemas

by Ramez Elmasri, Qing Li, Jack Fu, Yu-chi Wu, Babak Hojabri, Swathi Ande - In 21st International Conference on Conceptual Modeling (ER , 2002
"... XML was initially developed for document management, but it is becoming increasingly used for storing and exchanging all kinds of data on the Internet. In this paper, we introduce a design methodology for XML schemas that is based upon well-understood conceptual modeling methodologies. Because XML i ..."

is hierarchical (tree-structured), many different XML schemas (or document structures) can be generated from the same conceptual database schema. We describe algorithms for generating customized hierarchical views from EER model, creating XML schemas from hierarchical views, generating SQL queries corresponding

OCML Ontologies to XML Schema Lowering ⋆,⋆⋆

by Vlad Tanasescu, John Domingue, Liliana Cabral
"... Abstract. Ontologies are explicit specifications of a conceptualization intended for logical processing. They are used to express meaning and to apply it on otherwise less structured data. Nevertheless other models of organization and structure of knowledge, like database models and XML document def ..."

Rule-based generation of XML schemas from UML class diagrams

by Tobias Krumbein, Thomas Kudrass - In Berliner XML Tage 2003 , 2003
"... Abstract. We present an approach of how to automatically extract an XML document structure from a conceptual data model that describes the content of the document. We use UML class diagrams as the conceptual model that can be represented in XML syntax (XMI). The algorithm we present in the paper is ..."
Abstract - Cited by 9 (0 self) - Add to MetaCart
is implemented as a set of rules using XSLT stylesheets that transform the UML class diagram into an adequate XML Schema definition language (XSD). The generation of the XML Schema from the semantic model corresponds with the logical XML database design based on the fact that the XML Schema is the database

XTRACT: A System for Extracting Document Type Descriptors from XML Documents

by Minos Garofalakis, Aristides Gionis, Rajeev Rastogi, S. Seshadri, Kyuseok Shim - MOD , 20001999

An XML document can be accompanied by a Document Type Descriptor (DTD) which plays the role of a schema for an XML data collection. DTDs contain valuable information on the structure of documents and thus ha ..."

Automatic test data generation for XML Schema based partition testing

MAPPING RULES FOR ER TO XML USING XML SCHEMA Abstract

by Sung Jin, Woohyun Kang
"... The Extensible Markup Language (XML) has emerged as a de facto standard language for exchanging data among disparate information systems. Since the majority of data in the world is stored in databases, the conversion of such data into XML documents is indispensable for real world usage. In this pape ..."
Abstract - Add to MetaCart
. In this paper, we propose the algorithm for mapping the Entity Relationship model (ER model) to the XML document at the metadata level to address this conversion issue effectively. This is a progressive attempt to automatically generate the XML document from the conceptual database schema using the XML Schema
