Summary: The emergence of the Object Oriented and Relational paradigms and their widespread
adoption in software development highlighted the Object/Relational Impedance Mismatch,
caused by the difference in approach between the paradigms. Nowadays, the use of mapping
frameworks between the two approaches is state-of-the-practice due to the efficiency and
security they provide for development.
In this work, we present the Object/Relational Mapping Ontology (ORM-O), a reference
ontology in the ORM frameworks domain that aims to identify and represent the semantics
of object/relational mapping.
The ontology was developed following the SABiO method and modeled using OntoUML.
Its evaluation was carried out through verification and validation activities, answering
the competency questions previously raised and instantiating ontology concepts using
object/relational mapping code snippets, using a very popular ORM framework.
ORM-O was built within the scope of a project that aims to create a network of ontologies
about software development frameworks. Such ontologies will allow us to automate semantic
interoperability tasks, such as migrating code between frameworks, or specifying smells in
software architecture independently of framework or language, for example.
As a proof of concept, we also developed a migration tool that converts code from one
ORM framework to another (on different platforms) using ORM-O as an interlingua.
