One of the most popular challenges facing academia and industry is the development
of effective techniques and tools for maximizing the availability of data as the most
valuable source of knowledge. The internet has dominated as the core for
maximizing data availability and XML (eXtensible Markup Language) has emerged
and is being gradually accepted as the universal standard format for platform
independent publishing and exchanging data over the Internet. On the other hand,
there remain large amount of data held in structured databases and database
management systems have been traditionally used for the effective storage and
manipulation of large volumes of data. This raised the need for effective
methodologies capable of smoothly transforming data between different formats in
general and between XML and structured databases in particular. This dissertation
addresses the issue by proposing a two-way mapping approach between XML and
object-oriented databases. The basic steps of the proposed approach are applied in a
systematic way to produce a graph from the source and then transform the graph into
the destination format. In other words, the derived graph summarizes characteristics
of the source whether XML (elements and attributes) or object-oriented database
(classes, inheritance and nesting hierarchies). Then, the developed methodology
classifies nodes and links from the graph into the basic constructs of the destination,
i.e., elements and attributes for XML or classes, inheritance and nesting hierarchies
for object-oriented databases. The methodology has been successfully implemented
and illustrative case studies are presented in this document.
