Converting Relational Databases into Object-relational Databases. [PDF]

open access: yesThe Journal of Object Technology, 2010
This paper proposes an approach for migrating existing Relational DataBases (RDBs) into Object-Relational DataBases (ORDBs). The approach is superior to existing proposals as it can generate not only the target schema but also the data instances. The solution takes an existing RDB as input, enriches its metadata representation with required semantics ...
