Supporting Software Engineering Processes by Object-Relational Database Technology



OR-Benchmark



Nowadays database management systems (DBMS), esp. relational and object-relational DBMS, occur as components of large software systems. Usually, these complex systems are results of object-oriented development processes. Often the data management components of these large software systems are required to manage object-oriented data (structures). Since relational DBMS do not support object-orientation at all and the object-oriented concepts provided by object-relational DBMS mostly differ from those needed by the superordinated software system, corresponding mapping layers are needed bridging this object-orientation gap. In contrast to traditional benchmark approaches, we want build a benchmark system directly reflecting the above mentioned application scenario of DBMS. Not only the performance of the DBMS itself, but also the complexity and possible performance of the required mapping layer has to be quantified. Thus, our benchmark approach aims at assessing the contributions of (O)RDBMS to object-oriented software development.
