Open publisher page 2 citations

Abstract

The problem of database transformation from relational to object-oriented database occurs on using heterogeneous databases and when moving from a relational to an object-oriented database management system. The process of database transformation from one model to another can be divided into two phases: schema transformation from one model to another and data migration in accordance with schema transformation. Converting applications that work with a relational database into applications that work with an object-oriented database, the query translation problem occurs. In this paper we describe the main ideas of algorithms for implementation of all three phases, that enables automatization of the conversion processes.
