Motivation
Disk storage is far greater than main memory.
BUT: Accessing disk is much more time
consuming than accessing main memory.
To search and access information fro

Relations
A relation R on a set S maps every pair of elements in S to either TRUE or FALSE. For example, the greater than relation, >, is TRUE for the integer pair (5,3) (i.e., 5 > 3) but not for the
