Assuming a transaction load of predominantly schematic or canned transactions, exploitation of preknowledge of transaction access patterns leads to the concept of prefetching, i.e. loading data pages into the system buffer in advance and before a time-critical access request is issued.
Thus, the time behavior of a main memory database can be achieved. The justification of prefetching is only given by satisfying the time restriction in real- ...
