Framework for a complete migration of relational databases to other types of databases(object oriented OO, object-relational OR, XML)

摘要

This paper describes a Framework for achieving the migration of relational databases to other types of databases(OO, OR, XML), based on a meta-model which plays the core role of the framework in establishing migration, exploiting the different object concepts including inheritance, aggregation, and composition. The realization of the meta-model is based on the principle of semantic enrichment and metadata, considered as a flattened and extended relational database, migration starts with the migration of the relational physical schema to the target physical schema, next migrate the data from the relational database to the new database using the new physical schema. While reviewing some technology by proposing a comparative study, also making an overview of some approach of migration of different technologies, approaches and steps. Several passages of the RDB migration to other database types have been realized according to the Framework which proves its effectiveness.
