Integrity Maintenance in an Object-Oriented Database

We present an approach for integrating inter-object constraint maintenance seamlessly into an object-oriented database system. We develop a constraint compilation scheme that accepts declarative global specification of constraints, including relational integrity, referential integrity, and uniqueness requirements, and generates an efficient representation that permits localized processing. We d...

A Translation Algorithm for Effective RDB-to-XML Schema Conversion Considering Referential Integrity Information

In this paper, we propose a new relational schema (R-schema) to XML Schema translation algorithm that analyzes the cardinality between data values and patterns of user queries to resolve the implicit referential integrity issue. Many translation methods have been developed taking into account structural and/or semantic aspects. However, earlier methods have considered only the explicit referent...

Extensible Markup Language (XML) has become a standard for persistent storage and data interchange via the Internet due to its openness, self-descriptiveness and flexibility. This paper proposes a systematic approach to reverse engineer arbitrary XML documents to their conceptual schema – Extended DTD Graphs ― which is a DTD Graph with data semantics. The proposed approach not only determines t...

A Domain Integrity Constraint Control for XML Documents

Integrity constraints for XML documents are mainly defined through XML schemas: DTD and XML Schema. However, XML schemas do not have support for all existing kinds of domain integrity constraints in SQL databases. This paper presents a control called XDC that aims at supporting domain integrity constraints that cannot be handled by XML schemas. It is composed by an XML language for domain integ...
