Association Relationship Transformation of XML Schemas to Object–Relational Databases
XML (eXtensible Markup Language) is fast emerging as the dominant standard for describing data and interchanging data between various systems and databases on the Internet. It offers the XML Schema definition language as formalism for defining the syntax and structure of XML documents provide rich facilities for defining and constraining the content of XML documents. Nevertheless, to enable eff...
متن کاملTransforming Extended Entity - Relationship Model into Object - Relational Database using Triple Graph Grammars
The entity-relationship and extended entity-relationship have been the most popular paradigms for conceptual database design. However, with the appearance of a new generation Object-relational database and UML, conceptual database modeling using the EER approach has not attracted much interest, although the EER model is still powerful when working with object-oriented databases. Therefore in th...
متن کاملTranslating Relational Schemas into Object-based/XML Schemas
This paper proposes an approach for translating an existing relational database (RDB) schema into relatively newer database (i.e., object-oriented, object-relational and XML) schemas, based on available standards. The approach is superior to existing proposals as it generates three different and equivalent target schemas. The solution takes an RDB as input, enriches its metadata representation ...
متن کاملReverse Engineering Relational Schemas to Object-Oriented Schemas
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 gathered either automatically or from the user. This paper presents an object-centered approach ...
متن کاملA New Approach for Semantic Integrity Constraints Representation in Enhanced Entity-Relationship and Relational Database Schemas
In this paper Semantic-Enhanced Entity Relationship (SEER) and Semantic – Relational Database (SRD) diagrams are proposed. SEER and SRD are extensions of Enhanced Entity Relationship (EER) and Relational Database (RD) diagrams respectively that are based on dealing with Semantic Integrity Constraints. EER and RD do not take semantic constraints in matter. A lots of information are lost because ...
