Example text

Database cracking [11] and adaptive merging [9]. Since both methods prove useful, a hybrid approach has also been proposed [12]. There is also a benchmark to compare adaptive indices [8]. In our research we focus on the object-relational mapping middleware (ORM) and its inherent optimisation potential. We showed that ORM could optimize analytic queries by materialization of partial aggregates [7]. We also described a programming interface to define aggregations worth materializing (called metagranules) and a query rewriting that facilitates using them.

Therefore, information on the performance of data interfaces would be helpful in deciding on the appropriate technology. 1 Related Work In the Internet one can find many articles, blogs and discussions comparing different ORM interfaces and various aspects of their practical application. In general, the discussion on ORM interfaces goes in two directions. First problem is how using any ORM interface influences the performance of database query and whole development process. Another discussion is which ORM framework is the best solution in terms of performance and other criteria that may be important for application development and maintaining.
