Bulk-Loading Techniques for Object Databases and an Application to Relational Data

We present a framework for designing, in a declarative and flexible way, efficient migration programs and an undergoing implementation of a migration tool called RelOO whose targets are any ODBC compliant system on the relational side and the 02 system on the object side. The framework consists of (i) a declarative language to specify database transformations from relations to objects, but also physical properties on the object database (clustering and sorting) and (ii) an algebrabased program rewriting technique which optimizes the migration processing time while taking into account physical properties and transaction decomposition. To achieve this, we introduce equivalences of a new kind that consider side-effects on the object database.
