Measuring the contributions of (O)RDBMS to object-oriented software development

We describe a new benchmark approach which is needed for two reasons. First, today´s computer systems almost exclusively use relational database management systems (DBMS), and, besides (purely) relational DB technology, only the new trend of object-relational technology is expected to obtain practical relevance. Second, today´s (complex) software systems are developed in an object-oriented way. Thus, a benchmark approach is needed assessing the contributions of (object-)relational DBMS to object-oriented software development. Consequently, such a benchmark does not only have to `measure´ the efficiency of the DBMS itself but does also have to take the overhead to be spent for mapping object-oriented data structures to the DBMS interface into account. We describe how our approach achieves this goal and report on first measurement results
