A prefetching technique for object-oriented databases
[chapter]
1997
Lecture Notes in Computer Science
Preserved Fulltext
We assigned transition probabilities to object relationships and applied the hitting times method to compute page probabilities and the mean time to access a page. ...
Access pattern of object-oriented databases are often complex and usually hard to predict accurately. ...
The main novelty of this work is the synthesis of analysing object relationships and statistical information for predicting page accesses. ...
