This Chapter deals with basic introductory concepts on translating the Entity-Relationship Data Model relationship types from an enriched XML schema to an object-oriented one. Database migration is a process wherein all the components of a source database are converted to their equivalents in the environment of the target one.
We chose oriented object database as a target database
because there are many common characteristics between XML and object-oriented
model, Thus the mapping from XML data into object-oriented databases is more
interesting; also the object-oriented data bases have become very widespread
and acceptable, they offer an evolutionary approach, so we agree that it is
time to develop a translation between XML and OO databases. Our work is focused
on preserving Semantics transformation of association relationships, we
describe set of rules to create ODL classes from an enriched XML schema, the
experimental show that the approach is feasible, and results are the same, the
source database is transformed into target one without loss of data. Our future
work, will be on developing a better mapping taking into account the definition
ODL allowing to establish correspondences between concepts that were not taken
into account such as inheritance relationship, besides the addition of these
concepts allows to specifically identifies semantic links between elements.
