Abstract:
The number of XML documents is
growing rapidly on the Web because Extensible
Markup Language (XML) becomes a standard
format for exchanging and representing data
over the Internet. But most of the data are stored
in structured databases such as relational and
object-oriented databases. Therefore, data model
heterogeneity and schema heterogeneity makes
the main challenging tasks for data transferring
on the Web and to get the standard method.
Fortunately, XML schema provides the
converting the physical data to XML format is
more accurately and efficiently. This paper
proposes a framework for generating semantic
XML schema from relational and object-oriented
databases schema through the concept of
Extended Entity Relationship (EER) model and
Unified Modeling Language (UML class
diagram). To avoid the loss of information,
schema matching step is used to compare the
XML schemas generated by each model and
merge them to provide good result of schemas.
