| Abstract | The application of materialised object–oriented views in object– relational data warehousing systems is promising. In this paper we propose a novel technique for the materialisation of method results in object–oriented views, called hierarchical materialisation. When an object used to materialise the result of method m is updated, then m has to be recomputed. This recomputation can use unaffected intermediate materialised results of methods called from m, thus reducing a recomputation time. The hierarchical materialisation technique was implemented and evaluated by a number of experiments concerning methods without input arguments as well as methods with input arguments. The results showed that hierarchical materialisation reduces method recomputation time. Moreover, materialising methods with input arguments of narrow discrete domains introduces only a small time overhead. |
