| Research Abstract |
Formerly, database applications required to store all the data into a hard disk, however, after 2000's, middle or large-scale practical databases become possible to be stored in the main memory of PCs. In this project, we proposed and developed a new method of high-speed database analysis with a very large-scale monolithic main memory. Our method is based on Binary Decision Diagram (BDD), which is a new type of compressed graph structure for efficiently manipulating large-scale combinatorial data.
