Abstract
One of the most important problems of object-oriented database management systems is efficiency. This problem becomes particularly evident with applications managing large amounts of data having complex structures and varying sizes (e.g. multimedia data). PESOS (Performance Evaluation System for Object Stores) is a software tool for estimating the cost of associative retrieval in very large and complex object stores. It enables to model various object storage organizations with respect to specific characteristics of the secondary memory hardware. It provides a simple language to specify queries on the object store structures and returns quantitative evaluations, using analytical methods, of the access performance.
This work was funded by the ESPRIT Basic Research Action Project No. 6309, FIDE-2 (Formally Integrated Data Environment) and Progetto Finalizzato Calcolo Parallelo of C.N.R.
The work was done at IEI-CNR in Pisa while on leave from the Technical University of Brno.
