| Summary: | A multidatabase is a confederation of pre-existing distributed, heterogeneous,
and autonomous database system. Obviously, the integration process is essential
in the effort of forming a distributed, heterogeneous database system. This
process generally consists of two main phases, which are conceptual schema
translation phase followed by the integration phase. This paper presents a
translation approach to convert relational database schema to object-oriented
database schema. The translation approach consists of a set of translation rules,
which is based on inclusion dependencies, key attributes and types of attributes.
A database schema translation tool prototype, called RETOO (RElational-ToObject-
Qriented) is then developed based on the proposed translation approach.
RETOO receives a relational database schema as input data and generates an
object-oriented database schema as the output. The translation approach is not
only able to maintain the semantics of the relational database schema, but also
enhance the semantics of the translated object-oriented schema via objectoriented
data modeling concepts. |
