In this paper, we introduce the concept of XML document views over relational schemas.
Matching of XML Schemas and Relational Schemas
"... XML is widely used for data exchange between relational databases. Generic exchange tools are based on mappings between the elements of both schemas. Despite the benefits of using generic tools, the manual definition of the mappings can become a time consuming and error-prone task. Given this scenar ..."

Automatic Importation of Relational Schemas in Pegasus
- PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON DATA ENGINEERING
, 1993
"... This paper describes a technique for importing automatically an external relational schema into Pegasus, a heterogeneous, multidatabase system. The Pegasus data model is a functional object model which supports specialization, object-identity, and nested aggregation. The import algorithm generates t ..."

XViews: XML views of relational schemas
- In Proceedings of the Workshop on Databases and Expert System Applications
, 1999
"... The Mediation of Information using XML (MIX) project is a joint effort between the the San Diego Supercomputer Center (SDSC) and the Database Lab at the University of California San Diego where we are investigating the use of XML as the medium for information modeling and information interchange amo ..."

among heterogeneous information sources. Relational databases represent an important type of information source. In this paper, we discuss issues in providing XML document views of relational schemas. We refer to these as, XViews. We also discuss related work from a project funded by DARPA and the US
Capturing XML Constraints with Relational Schema
"... The use of XML as the common format for representing, exchanging, and accessing data poses many new challenges to XML storage systems. One way to this goal is to store XML data in relational databases in order to use relational database techniques. Although several approaches exist, they focus only ..."

on XML data aspects and ignore semantic constraints. In the paper, we analyze structural and semantic constraints in XML, and then we discuss how to capture and map these constraints with relational schema. Comparing with existing methods, our approach can preserve more XML constraints and reduce nesting
Reverse Engineering Relational Schemas to Object-Oriented Schemas
, 1996
"... Due to the wide use of object-oriented technology in software development, reverse engineering of relational schemas to object-oriented schemas is gaining a lot of interest. One of the major problems with existing approaches for this schema mapping is the extensive amount of information that must be ..."

XML Constraints Preservation in Relational Schema
"... XML has become the universal format for the representation and exchange of information over the Internet, but relational database is still the dominant data repository. So it is also useful in information exchange and data integration for preserving the semantics of data originating in relational da ..."

to guarantee these constraints. At last we present our methods to preserve these constraints with relational schema. Comparing with other methods, our approach can preserve more XML constraints, reduce nesting and redundant data, and avoid storing bad DTDs. 1.
Mapping XML and Relational Schemas with Clio
- In Proceedings of the 18th International Conference on Data Engineering
, 2002
"... Merging and coalescing data from multiple and diverse sources into different data formats continues to be an important problem in modern information systems. Schema Matching, the process of matching elements of a source schema with elements of a target schema, and Schema Mapping, the process of crea ..."

We demonstrate Clio, a semi-automatic schema mapping tool developed at the IBM Almaden Research Center. In this demonstration we showcase Clio’s mapping engine that allows mapping to and from relational
Title: Translating relational schema with constraints into XML schema
