Abstract

Important data base system resources are the data items that can be viewed as logical resource, and CPU, disks and the main memory which are physical resources [Garcia-Molina et al. 1992]. Though, the cost of main memory is dropping rapidly and its size is increasing, the size of database is also increasing very rapidly. In real time applications, where the databases are of limited size or are growing at a slower rate than memory capacities are growing, they can be kept in the main memory. However, there are many real time applications, which handle large amount of data and require support of an intensive transaction processing. The amount of data they store is too large (and too expensive) to be stored in the main memory.
